What Is Phosphoric Acid Trisdecyl Ester?

Phosphoric Acid Trisdecyl Ester, also referred to as tridecyl phosphate, is an organophosphate ester formed by the esterification of phosphoric acid with three decanol (decyl alcohol) molecules. It belongs to the broader class of trialkyl phosphates, which are characterized by a central phosphorus atom bonded to three alkoxy groups via oxygen linkages.

As a long-chain trialkyl phosphate, this compound exhibits high hydrophobicity, relatively low volatility, and high thermal stability compared to shorter-chain analogues. These properties make it a versatile reagent in research and industrial contexts. Aladdin Scientific supplies this compound under SKU P342333, cross-referenced to Santa Cruz catalog number sc-478911.

Key Chemical and Physical Properties

Phosphoric Acid Trisdecyl Ester is characterized by the following general physicochemical attributes typical of long-chain trialkyl phosphates:

• Molecular formula: C₃₀H₆₃O₄P (based on three n-decyl chains; actual isomeric composition should be confirmed from the certificate of analysis)
• Chemical class: Organophosphate / trialkyl phosphate ester
• Appearance: Typically a colorless to pale yellow oily liquid at room temperature
• Solubility: Low water solubility; miscible with common organic solvents such as hexane, toluene, and chloroform
• Thermal stability: High boiling point expected due to long alkyl chains, suitable for high-temperature processes

Note: Specific numerical values for boiling point, density, viscosity, and refractive index should be verified against the product certificate of analysis (CoA) available from Aladdin Scientific.

Applications in Research and Industry

Phosphoric Acid Trisdecyl Ester finds utility in several research and technical areas:

• Solvent extraction: Long-chain trialkyl phosphates are well-established extractants in liquid-liquid extraction systems, particularly for metal ion separation and purification workflows in analytical and radiochemical laboratories.
• Plasticizer: Trialkyl phosphate esters are used as plasticizers in polymer science to improve flexibility and processability of polymer matrices.
• Lubricant and hydraulic fluid additive: The high thermal stability and hydrophobicity of long-chain phosphate esters make them suitable as lubricant additives or base components in specialized fluid formulations.
• Research reagent: Available as a high-purity research-grade chemical for use in mechanistic studies, formulation research, and method development.

Researchers should consult primary literature for specific protocols and confirm suitability of the compound for their intended application.

Safety, Handling, and Storage

As with all organophosphate compounds, appropriate safety precautions must be observed when handling Phosphoric Acid Trisdecyl Ester:

• Personal protective equipment (PPE): Wear chemical-resistant gloves, safety goggles, and a laboratory coat. Use in a well-ventilated area or fume hood.
• Skin and eye contact: Avoid direct contact. In case of contact, rinse thoroughly with water and seek medical advice if irritation persists.
• Ingestion/inhalation: Avoid ingestion and inhalation of vapors or aerosols.
• Storage: Store in a tightly sealed container in a cool, dry, well-ventilated location, away from heat sources and incompatible materials (strong oxidizers, strong bases).
• Disposal: Dispose of in accordance with local regulations for organophosphate-containing waste.

Important: Always consult the Safety Data Sheet (SDS) for P342333 provided by Aladdin Scientific before use. Specific hazard classifications and regulatory data should be verified from the official SDS.
