Biological Roles

Item-specific note

• This product is a synthetic, Boc-protected derivative for laboratory research. It is not intended for biological administration.

General biochemical context (literature)

• Tyrosine background: L-Tyrosine is a proteinogenic amino acid involved in protein synthesis and as a precursor to catecholamines and melanin. Its phenolic side chain participates in hydrogen bonding, acid–base catalysis, and redox processes in enzymes.
• Tyrosinol vs tyrosine: Reduction of the carboxylate to a primary alcohol eliminates the zwitterionic character and changes acidity/basicity and hydrogen-bond topology. As a result, tyrosinol derivatives are often used as stable isosteres of reduced amide/carboxylate motifs in peptidomimetics and probes.
• Boc protection: The Boc carbamate masks the amine, suppressing ionic interactions and enabling organic-phase transformations. Under physiological-like acidic conditions, Boc can cleave, but such conditions are not part of biological roles—this is a synthetic protecting strategy.

Takeaway

• Boc-DL-Tyrosinol has no native biological role; its relevance is as a chemical intermediate that models or modifies the behavior of tyrosine-derived structures in strictly in vitro chemical studies.

Buffer Applications

Not typically applicable. Boc-DL-Tyrosinol is a neutral organic building block with low water solubility and no buffering capacity in the biological pH range. For aqueous work, it is generally handled as an organic solution or after deprotection to the free amine, which may then participate in buffer systems. Refer instead to the Synthetic Utility and Reaction Conditions sections for practical use.

Green Alternatives

Context: Boc-DL-Tyrosinol is a solid building block rather than a process solvent. Greener practice focuses on solvent selection, protecting-group strategy, and oxidation/activation choices during its use.

Greener choices (literature/general)

• Solvents:
  • Prefer 2-MeTHF over THF and DCM where feasible (similar polarity; partially bio-based; easier phase separation).
  • Use ethyl acetate or isopropanol for workups and recrystallization instead of chlorinated solvents.
  • Replace DMF/DMSO with MeCN or propylene carbonate when reaction compatibility permits.
• Boc deprotection:
  • Minimize TFA volume; capture and neutralize vapors. Consider alternative acid media (HCl in dioxane) if downstream salt forms are desired, albeit with higher hazard to personnel.
• Oxidations of –CH2OH:
  • TEMPO/NaOCl (bleach) in biphasic water/ethyl acetate or MeCN offers a greener alternative to chromium(VI) or Swern conditions.
• Phenol protection/alkylation:
  • Use carbonate bases (K2CO3, Cs2CO3) and greener solvents (acetone, 2-MeTHF) instead of strong bases in polar aprotics.

Trade-offs

• 2-MeTHF may reduce substrate solubility versus DCM/THF; reaction rates can be slower.
• Aqueous TEMPO/bleach systems require careful pH control and may over-oxidize benzylic positions if not monitored.

Snapshot comparison (literature; qualitative)

• Conventional: DCM/THF, DMF; Dess–Martin or Swern; TFA deprotection.
• Greener: 2-MeTHF/EtOAc/MeCN; TEMPO/NaOCl; solvent recycling; minimal TFA with effective scrubbing.

Pharmaceutical Uses

Item-specific note

• No pharmacopeial status or excipient designation is provided. Not specified for this item; refer to CoA/Spec Sheet.

General context (non-clinical; literature)

• Role as an intermediate: Boc-DL-Tyrosinol is suitable as a non-GMP research intermediate in the synthesis of small-molecule leads, antibody–drug conjugate linkers (phenolic handle), and peptidomimetics where a reduced C-terminus is desired.
• Protecting-group strategy: Boc protection offers acid-labile, base-stable orthogonality relative to phenol and primary alcohol, enabling stepwise introduction of pharmacophores or linkers.
• Salt forms and formulations: Upon Boc deprotection, the free amine can form HCl or TFA salts to improve handling and crystallinity of intermediates. Such operations are process development steps and not final dosage form claims.
• Regulatory considerations: For any use beyond research, material would need defined specifications (purity profile, residual solvents, elemental impurities), validated analytical methods, and appropriate change control. Chiral composition (DL here) must be managed if target routes require specific enantiomers.

Important

• No therapeutic or clinical claims are made. This product is provided strictly for research and laboratory synthesis.

Physical Properties

Item-specific (Product Data)

• Appearance: Not specified for this item; refer to CoA/Spec Sheet.

Computed/Literature values (for N-Boc-tyrosinol; approximate, not item specifications)

• Molecular weight: ~268.33 g/mol (calculated from C14H22NO4)
• Expected physical state: organic solid at ambient conditions (literature/analogy for Boc-protected amino alcohols)
• pKa (phenol): typically ~10 (literature, phenolic OH); carbamate N–H is much less basic than amines (conjugate acid pKa typically <2, literature trend)
• LogP: moderate polarity expected; Boc and phenol reduce aqueous solubility while –CH2OH adds hydrogen bonding (qualitative, literature rationale)
• Solubility profile (qualitative, literature):
  • Good: dichloromethane, chloroform, THF, acetonitrile, ethyl acetate, methanol, DMF, DMSO
  • Limited: water (phenol and carbamate H-bonding partially offset by bulky Boc)
  • Poor: aliphatic hydrocarbons (hexanes/heptane)

Notes for practitioners

• Refractive index, melting point, boiling point, density: Not specified for this item; refer to CoA/Spec Sheet or determine experimentally.
• Hygroscopicity: Boc carbamates are generally not strongly hygroscopic, but the free phenol and alcohol can hydrogen bond; store dry to prevent adventitious moisture uptake.
• Solid-state behavior: Racemates often crystallize readily; however, polymorphism and solvate formation can occur depending on solvent and crystallization conditions (literature generality).

Quality and Grades

Item-specific (Product Data)

• Grade/Purity: Not specified for this item; refer to CoA/Spec Sheet for assay, residual solvents, and related substances.
• Stabilizers/Additives: Not specified for this item; refer to CoA/Spec Sheet.

General guidance on quality for Boc-protected building blocks

• Identity verification: 1H/13C NMR (diagnostic Boc tert-butyl singlet near δ 1.4 ppm; carbamate carbonyl ~155–157 ppm), phenolic OH often broad/variable; HRMS to confirm [M+H]+ ~269.33.
• Chiral composition: This listing is DL (racemic). If enantioenriched material is required, request L- or D-tyrosinol derivatives with documented ee by chiral HPLC.
• Residual water/peroxides/metals/UV cutoff: Not specified for this item; refer to CoA/Spec Sheet.
• Typical impurities (general): Unprotected tyrosinol, over-protected carbonate species, Boc anhydride residues, regioisomeric O-Boc side products, and oxidized benzylic species. Appropriate purification (flash chromatography, recrystallization) and analytical release tests (HPLC purity, NMR) are recommended.
• What “research grade” implies: Suitable for synthetic and analytical R&D. For GMP or pharma manufacturing, require full specifications (ICH Q3A/B, elemental impurities per ICH Q3D) and a CoA aligned to your internal quality system.

Reaction and Applications

Focus: Boc-DL-Tyrosinol is a versatile protected amino alcohol derived from tyrosine. It serves as a chiral-agnostic (racemic) building block in peptide-mimetic synthesis, linker design, and derivatization of phenolic scaffolds.

Representative applications (literature/general)

• Amine protection platform: Boc group provides acid-labile protection during modifications of the phenol and primary alcohol. Subsequent TFA deprotection unmasks the amine for coupling.
• Phenolic elaboration:
  • O-Alkylation or O-acylation to access ethers/esters (K2CO3/alkyl halides; acyl chlorides/anhydrides with base). Phenol selectivity under mild base is typically superior to the primary alcohol.
  • Electrophilic aromatic substitution on the ring (nitration, sulfonylation) directed by the phenol’s activating/ortho-para directing character (typically para is occupied; ortho positions reactive).
• Alcohol functionalization:
  • Mitsunobu reaction to invert/convert the primary alcohol to a wide range of nucleophile-substituted products (DEAD/DIAD, PPh3).
  • Oxidation to aldehyde/acid for further homologation (Dess–Martin, TEMPO, or Swern).
  • Conversion to halide (Appel or PBr3) for subsequent substitution/coupling.
• Linker chemistry: The benzylic–aliphatic primary alcohol provides a handle for carbonate/carbamate/urea formation to attach to polymers or drug-linker constructs while the Boc-protected amine preserves orthogonality.
• Peptidomimetic design: Incorporation into side-chain-modified residues, “reduced amide” analogs, and probe molecules where the carboxylate of tyrosine is replaced by an alcohol to modulate H-bonding and stability.

Practical tips

• Keep strictly anhydrous for moisture-sensitive steps (e.g., acid chloride couplings, Mitsunobu).
• Manage phenol vs alcohol selectivity with base strength and solvent; protect phenol (e.g., as benzyl or silyl ether) if needed for exclusive primary alcohol chemistry.

Reaction Conditions

General conditions (literature; guidance only, not item specifications)

• Boc deprotection: TFA (20–100% v/v) in DCM at 0–25 °C, 0.5–2 h; scavengers (anisole, thioanisole) can mitigate side reactions. Work up by evaporation and basification or direct salt formation.
• Phenol O-alkylation: K2CO3 (2–3 equiv) with alkyl bromide/iodide in DMF or MeCN, 20–60 °C, 2–16 h. Cs2CO3 for hindered substrates. Monitor to suppress competing primary alcohol alkylation; phenol protection may be used for full selectivity.
• Phenol acylation: Acyl chloride (1.1–1.5 equiv) with pyridine or Et3N in DCM/MeCN, 0–25 °C, 1–4 h; DMAP (cat.) accelerates.
• Primary alcohol transformations:
  • Mitsunobu: DEAD/DIAD (1.2–1.5 equiv), PPh3 (1.2–1.5 equiv), THF/DCM, 0–25 °C, 2–6 h, with nucleophile (1.5–2.0 equiv).
  • Appel halogenation: CBr4 (1.2–1.5 equiv)/PPh3 (1.2–1.5 equiv) in DCM, 0–25 °C.
  • Oxidation: Dess–Martin periodinane (1.3 equiv) in DCM, 0–25 °C, 0.5–2 h to aldehyde; or TEMPO (1–5 mol%), NaOCl (1.5–2.0 equiv), KBr (cat.) in biphasic H2O/EtOAc, pH ~9–10, 0–10 °C.
• Aromatic electrophilic substitution: Iodination (NIS) in MeCN/AcOH at 0–25 °C; sulfonylation (ClSO3H or TsCl/pyridine) under controlled conditions; protect alcohol if needed.

Selectivity/stability notes

• Boc stability: Stable to bases such as K2CO3, DIPEA, and to many oxidations; cleaves in strong acid (TFA, HCl). Avoid extended heating >60 °C in strongly basic protic media.
• Phenol vs alcohol: Under weak base, phenolate forms selectively; for exclusive primary-alcohol reactions, mask phenol (Bn, TBDPS).

Typical workup/purification

• Quench oxidants/reagents cautiously; extract into EtOAc or DCM; wash with brine/bicarbonate; dry (Na2SO4 or MgSO4); concentrate and purify by flash chromatography (EtOAc/hexanes or DCM/MeOH gradients).

Safety and Handling

Item-specific (Product Data)

• GHS classification, signal word, pictograms, H-statements: Not specified for this item; refer to SDS.
• Storage: Room temperature; shipped under normal conditions (per Product Data).
• Research Use: For research use only.

General laboratory safety guidance (literature/general)

• Anticipated hazards: Organic carbamates and phenolic compounds can cause skin/eye irritation and may be harmful if swallowed or inhaled. Treat as a combustible organic solid. Avoid generation of dust/aerosols.
• PPE: Lab coat, safety glasses or goggles, and appropriate chemically resistant gloves (e.g., nitrile). Use in a chemical fume hood to avoid inhalation of dust or solvent vapors during handling and reactions.
• Incompatibilities: Strong acids (may deprotect Boc under acidic conditions, releasing CO2 and tert-butanol); strong bases (can deprotonate phenol/alcohol; prolonged exposure may cause transcarbamoylation/hydrolysis). Strong oxidants may oxidize the benzylic alcohol or phenol. Isocyanate-forming reagents can react with residual amine if deprotected.
• First aid (overview; consult SDS):
  • Skin/eye contact: Rinse with water for ≥15 min; remove contaminated clothing; seek medical attention if irritation persists.
  • Inhalation: Move to fresh air; seek medical attention if symptoms occur.
  • Ingestion: Rinse mouth; do not induce vomiting; seek medical attention.
• Fire safety: Use CO2, dry chemical, or foam. Combustion may produce CO/CO2 and nitrogen oxides.
• Waste: Collect organics and aqueous washes per institutional and local regulations; avoid drain disposal.

Solvent Selection

Applicability: Boc-DL-Tyrosinol is a polar, multifunctional organic solid. Solvent choice impacts solubility, selectivity (phenol vs alcohol reactivity), and protecting-group stability.

General solvent behavior (literature)

• Polarity class: Polar protic/aprotic compatible substrate; dissolves well in mid-polar organics.
• Miscibility/solubility (qualitative):
  • Good: DCM, CHCl3, THF, EtOAc, MeOH, MeCN, DMF, DMSO
  • Limited: Toluene; poor in aliphatic hydrocarbons
  • Aqueous solubility: Low to moderate depending on pH (enhanced as phenolate under basic conditions)
• Phenol vs alcohol: In basic media (K2CO3, Cs2CO3 in DMF/acetone), phenol deprotonates more readily than the primary alcohol, enabling selective O-arylation/O-alkylation at the phenol.

When to choose specific solvents

• O-Alkylation (phenol): DMF, DMSO, or acetone with K2CO3; MeCN for cleaner SN2 with soluble bases.
• Mitsunobu functionalization of the primary alcohol: THF, toluene, or DCM with DEAD/DIAD and PPh3.
• Boc deprotection: DCM or CH2Cl2/anisole with TFA at 0–25 °C; avoid nucleophilic solvents that can trap carbocations.
• Oxidations (–CH2OH to –CHO/–CO2H): DCM for Dess–Martin; MeCN or acetone for TEMPO/bleach; MeCN/DCM for Swern.

Comparison snapshot (literature)

• DCM: Excellent solubility, inert; environmental concerns.
• MeCN: Polar aprotic, good for SN2; higher boiling point aids control.
• THF/2-MeTHF: Strong solvating ability; 2-MeTHF offers greener profile with similar performance.

Storage and Reconstitution

Item-specific (Product Data)

• Storage conditions: Room temperature.
• Shipped in: Normal conditions.

General handling guidance (literature/general)

• Container: Store in a tightly closed, chemically compatible container (amber glass recommended) with a desiccant to limit moisture. Inert atmosphere (nitrogen/argon) is beneficial for long-term stability, especially if repeatedly opened.
• Stability: Boc carbamates are generally stable for extended periods at ambient temperature when dry and protected from strong acids/bases. Avoid prolonged exposure to acidic vapors (e.g., HCl, TFA) which can deprotect the amine.
• Reconstitution: Not applicable—solid building block. Prepare solutions freshly in dry organic solvents (e.g., DCM, MeCN, THF, DMF, DMSO) appropriate to the intended transformation.
• Solution stability: In neutral, anhydrous organic solvents, solutions are typically stable over typical working times. Avoid storing solutions containing acid; Boc cleavage can occur. For stock solutions in DMSO/DMF, store at 2–8 °C and use within a few days to minimize degradation.
• Freeze–thaw: Not relevant. If solutions must be stored, aliquot to avoid repeated warming cycles.

Always refer to the product’s CoA and SDS for authoritative storage, stability, and safety information.

Structure and Identity

Item-specific (Product Data)

• SKU: B349440
• Product name: Boc-DL-Tyrosinol
• CAS: 282100-80-5
• InChIKey: 184274 (as provided)
• Storage conditions: Room temperature; shipped under normal conditions

Computed/Literature (general chemical identity; not item-specific specs)

• Synonym: N-Boc-DL-tyrosinol; tert-butyl (DL)-tyrosinol carbamate
• Molecular formula (calculated for N-Boc-tyrosinol, racemate): C14H22NO4
• Molecular weight (calculated): ~268.33 g/mol
• SMILES (racemic, no stereochemistry implied): CC(C)(C)OC(=O)NC(CH2OH)CH2c1ccc(O)cc1
• 2D structural description: A para-hydroxyphenyl ring (p-phenol) is benzylic to a two-carbon side chain bearing (i) a secondary nitrogen protected as a tert-butoxycarbonyl (Boc) carbamate and (ii) a terminal primary alcohol (–CH2OH). The aromatic ring carries a phenolic OH at the para position relative to the benzylic linkage. No defined stereocenter assignment (DL mixture).

Key structural features (general)

• Functional groups: phenol (Ar–OH), primary aliphatic alcohol (–CH2OH), secondary amine masked as Boc carbamate (–NH–C(=O)–O–tBu), benzylic methylene (Ar–CH2–).
• Stereochemistry: The alpha carbon to nitrogen is stereogenic in the L/D tyrosinol scaffold; this product is DL (racemic), so enantiomeric mixture without optical activity expected.
• Protecting-group logic: Boc carbamate provides base-stable, acid-labile amine protection compatible with many transformations on the phenol and primary alcohol.

Synthetic Utility

Functional handles and orthogonality

• Amine (Boc-protected): Acid-labile; allows manipulations of phenol and primary alcohol under basic/neutral or mildly oxidative conditions without deprotection. Post-deprotection, couples readily via amide-bond formation (HATU/EDC) or urea/carbamate formation.
• Phenol: More acidic than the primary alcohol; can be selectively deprotonated for O-alkylation, O-acylation, or converted to aryl triflate/mesylate for cross-coupling (e.g., Buchwald–Hartwig after activation).
• Primary alcohol: Convertible to halides (Appel, PBr3), sulfonates (tosylate/mesylate), carbonates, or oxidized to aldehyde/acid for chain extension.

Named/typical transformations (literature)

• Mitsunobu reaction: Diversify the primary alcohol with inversion; install azide, thioesters, carboxylates, or other nucleophiles.
• Dess–Martin or TEMPO oxidation: Access aldehyde carboxyl bioisosteres for further Wittig/HWE homologations.
• O-Benzylation/O-silylation of phenol: Temporary protection to enforce chemoselectivity at the aliphatic alcohol.
• Carbamate/urethane chemistry: Primary alcohol to carbonate linker; after Boc removal, intramolecular or intermolecular urea formation possible.
• Electrophilic aromatic substitution: Sulfonation, nitration, or iodination ortho to phenol (para is occupied) to introduce handles for cross-coupling.

Retrosynthetic value

• Serves as a tyrosine surrogate lacking the carboxylate, enabling “reduced amide” analogs of peptides and tuning of polarity/lipophilicity.
• Racemic nature (DL) simplifies access for non-stereospecific targets; enantiospecific synthesis can proceed from L- or D-tyrosine-derived precursors when required.

Practical notes

• Control chemoselectivity by staged protection if necessary (e.g., protect phenol as Bn ether before primary-alcohol oxidation).
• Avoid strong acids when Boc retention is required; avoid strong bases in protic solvents to limit carbamate cleavage.
