Chemical Identity and Structure

1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane (SKU: B152192) is a symmetric bifunctional monomer consisting of a central 2,2,3,3,4,4,5,5-octafluorohexane-1,6-diol backbone esterified with two acryloyl groups at each terminal hydroxyl position. The eight fluorine atoms arranged along the central carbon chain constitute a dense perfluorinated segment that dramatically lowers surface energy, increases chemical inertness, and enhances thermal stability relative to non-fluorinated analogs. The two terminal acrylate groups provide reactive sites for free-radical crosslinking, making this compound an effective difunctional monomer in polymer network formation. Its molecular architecture combines the reactivity of conventional acrylates with the performance attributes of fluorinated materials, positioning it as a specialty reagent at the interface of surface science, polymer chemistry, and materials engineering.

Applications in Research and Industry

This fluorinated diacrylate crosslinker finds application across several research and industrial domains:

• Fluoropolymer network synthesis: Used as a difunctional crosslinker to introduce fluorinated segments into acrylic polymer networks, enhancing hydrophobicity, oleophobicity, and resistance to aggressive solvents and acids.
• UV-curable coatings and films: Incorporated into UV-curable formulations to produce low-surface-energy coatings with anti-fouling, anti-icing, or anti-fingerprint properties on glass, metal, or plastic substrates.
• Hydrophobic and oleophobic surface modification: Blended with other acrylate monomers to tailor the wettability and contact angle of cured coatings for optical, microfluidic, or protective applications.
• Microfluidics and lab-on-chip: The low surface energy and chemical resistance of fluorinated networks make this crosslinker relevant for fabricating hydrophobic channels or barriers in microfluidic devices.
• Biomedical materials research: Fluorinated crosslinkers are explored in the design of antifouling surfaces and drug-delivery matrices, though specific biocompatibility data should be verified before biomedical use.

Handling, Storage, and Safety Guidelines

Researchers and lab managers should observe the following precautions when working with 1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane:

• Personal Protective Equipment (PPE): Wear appropriate chemical-resistant gloves (e.g., nitrile or neoprene), safety goggles, and a laboratory coat. Use a fume hood when handling or formulating with this reagent to minimize inhalation exposure to vapors or aerosols.
• Storage conditions: Store in a tightly sealed container in a cool, dry, well-ventilated area. Protect from direct light and heat sources to prevent premature polymerization. Keep away from strong oxidizing agents, bases, and peroxides.
• Inhibitor management: Acrylate monomers are typically supplied with a polymerization inhibitor (e.g., hydroquinone monomethyl ether). Verify inhibitor presence before use; inhibitor removal may be required for certain polymerization protocols but increases the risk of spontaneous polymerization.
• Spill management: In case of spill, absorb with an inert material, collect in a sealed container, and dispose of in accordance with local regulations for halogenated organic waste.
• Regulatory compliance: Consult the current Safety Data Sheet (SDS) provided by Aladdin Scientific for comprehensive hazard classifications, first-aid measures, and disposal guidance before use.

Note: Specific hazard classifications, GHS pictograms, and regulatory data should be confirmed from the official SDS for SKU B152192.

Protocol: Incorporating into UV-Curable Formulations

The following general protocol outlines the incorporation of 1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane as a crosslinker in a UV-curable acrylate coating formulation. Optimize reagent ratios and cure conditions for your specific application.

1. Formulation preparation: Weigh the desired amount of 1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane (B152192) under subdued light in a fume hood. Combine with your base acrylate monomer(s) and/or oligomers. Typical crosslinker loading ranges from 5–30 wt% depending on the targeted crosslink density and mechanical properties; optimize empirically.
2. Photoinitiator addition: Add an appropriate UV photoinitiator (e.g., Type I or Type II) at the supplier-recommended loading (commonly 1–5 wt% relative to total monomer mass). Mix thoroughly until homogeneous. Avoid prolonged exposure to ambient light.
3. Substrate preparation: Clean substrates with appropriate solvents and allow to dry. Apply the formulation by spin coating, bar coating, or drop casting, depending on the desired film thickness and uniformity.
4. UV curing: Expose the coated substrate to UV irradiation using an appropriate lamp (e.g., medium-pressure mercury lamp or LED at suitable wavelength). Cure time and intensity should be optimized; typical exposures range from a few seconds to several minutes depending on film thickness and initiator efficiency.
5. Post-cure evaluation: Assess crosslink density via solvent swelling or gel-fraction measurement. Evaluate surface properties (contact angle, scratch resistance) as appropriate.

Caution: Perform all steps involving uncured monomer in a well-ventilated fume hood. Dispose of uncured acrylate waste per institutional and regulatory guidelines.

Quality, Purity, and Procurement Considerations

When procuring 1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane (B152192) from Aladdin Scientific, researchers and procurement personnel should consider the following:

• Purity grade: Confirm the purity specification for your application. Higher-purity grades are generally preferred for reproducible research results and sensitive formulations. Consult the product certificate of analysis (CoA) for lot-specific purity data.
• Inhibitor content: Acrylate monomers are typically stabilized with a radical polymerization inhibitor. The CoA or product specification sheet will indicate the inhibitor type and concentration. This is critical for shelf-life management and for protocols requiring inhibitor removal.
• Packaging and quantity: Select appropriate package sizes to minimize freeze-thaw cycles and prolonged storage after opening. Aladdin Scientific offers research-scale quantities suitable for laboratory use.
• Verification of identity: Upon receipt, verify the reagent identity using available spectroscopic data (e.g., NMR, FTIR) if required by your quality management system.
• Shelf life: Store per the conditions listed on the label and SDS; monitor for any color change or increase in viscosity that may indicate inhibitor depletion or partial polymerization. Specific shelf-life data should be confirmed from the product label or CoA.

Frequently asked questions

What is 1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane used for?

It is primarily used as a bifunctional fluorinated crosslinker in the synthesis of hydrophobic and chemically resistant polymer networks, UV-curable fluorinated coatings, and surface-modification formulations where low surface energy and solvent resistance are required.

How should this fluorinated diacrylate be stored to maintain stability?

Store in a tightly sealed container in a cool, dry, well-ventilated area away from heat, direct light, and strong oxidizers. Acrylate monomers are typically supplied with an inhibitor to prevent premature polymerization; maintaining recommended storage conditions preserves inhibitor efficacy and extends shelf life. Consult the SDS and product CoA for lot-specific recommendations.

Is inhibitor removal necessary before using this compound in polymerization reactions?

Inhibitor removal is not always required and depends on the specific polymerization protocol and the inhibitor concentration present. For many UV-curing applications, the photoinitiator concentration and UV dose can overcome inhibitor effects without prior removal. However, for highly sensitive kinetic studies or when working at very low initiator concentrations, inhibitor removal by passing through an inhibitor-removal column may be necessary. Always confirm the inhibitor type and concentration from the CoA before deciding.

What solvents are compatible with 1,6-Bis(acryloyloxy)-2,2,3,3,4,4,5,5-octafluorohexane?

Fluorinated acrylate monomers of this type are generally soluble in common organic solvents such as acetone, ethyl acetate, tetrahydrofuran, and chlorinated solvents, and may also dissolve in fluorinated solvents. Solubility in water is expected to be very low due to the high fluorine content. Specific solubility data should be confirmed experimentally or from the product SDS, as exact values are not listed in the current source material.
