Hazard Identification

Signal Word: Warning
GHS Classification: Skin irritation, eye irritation, aquatic toxicant
Hazard Statements: Can cause skin and eye irritation with direct contact; vapors sometimes lead to headache or nausea in poorly ventilated areas; suspected waterway contaminant due to persistence of perfluorinated group; fire generates toxic fumes
Precautionary Statements: Handle with skin protection and safety eyewear; avoid inhalation of vapor; if working in a lab, ensure proper containment to prevent environmental escapes

Composition / Information on Ingredients

Main Component: 2-(Perfluorobutyl)Ethyl Acrylate, typically >95% by weight
Other Constituents: Trace acrylic acid or other process-related impurities
Chemical Family: Fluorinated acrylate ester

First Aid Measures

Inhalation: If headache or dizziness arises, move to fresh air and allow time for symptoms to subside; persistent symptoms call for medical checkup
Skin Contact: Remove contaminated clothing, wash skin with copious running water and mild soap; check for irritation and treat with moisturizer if dryness follows
Eye Contact: Rinse purposefully under a gentle, running stream of water for at least 15 minutes; do not rub eyes, medical attention if discomfort remains
Ingestion: Medical intervention suggested if material is swallowed; rinse mouth—not recommended to induce vomiting due to aspiration risk

Fire-Fighting Measures

Suitable Extinguishing Media: Use CO2, foam, or dry powder extinguishers; water spray helps cool exposed containers but large spills call for foam barrier
Specific Hazards: Burning releases acrid fumes of hydrogen fluoride and carbon oxides; vapor can accumulate and flash if nearby ignition sources exist
Protective Equipment: Self-contained breathing apparatus and gear impervious to chemical splashes; firefighters often need chemical-resistant gloves and boots for runoff

Accidental Release Measures

Personal Precautions: Isolate small spills with absorbent material and ventilate area well; avoid contact with skin and use goggles or shield during cleanup
Environmental Measures: Prevent product from entering drains, soil, or waterways due to the persistence of perfluorinated tail
Clean-Up Procedures: Absorb spill with inert material like sand or clay, transfer to sealed steel drums for safe disposal; wash area with soapy water and ventilate

Handling and Storage

Handling: Work in a chemical fume hood or outdoor space if possible; keep containers tightly closed after use; change gloves and protective clothing often to avoid carryover
Storage: Store at ambient temperature in original tightly sealed containers; keep away from incompatible chemicals such as acids, alkalis, strong oxidizers; minimize temperature fluctuations to avoid condensation in vapor space which can lead to hydrolysis

Exposure Controls and Personal Protection

Engineering Controls: Labs always benefit from active ventilation and local exhaust; use of glove boxes or inert atmosphere systems common in scale-up settings
Personal Protective Equipment: Chemical safety glasses, nitrile or PVA gloves, full-sleeve lab coat impervious to liquids; emergency eye wash and safety shower recommended where volume in use is significant
Occupational Exposure Limits: No established threshold limit for this exact compound; use conservative exposure limits based on similar acrylate or fluorinated chemicals

Physical and Chemical Properties

Appearance: Clear, colorless-to-pale yellow liquid
Odor: Subtle, acrid or ethereal
Boiling Point: Around 150–200°C estimated based on related perfluoroalkyl acrylates
Solubility: Insoluble in water, soluble in common organic solvents (acetone, toluene, ethyl acetate)
Vapor Pressure: Moderately low at room temperature—handling in ventilated areas helps control
Density: Generally higher than typical acrylates due to perfluorinated tail, estimated 1.2–1.5 g/cm³
Other Notable Properties: High thermal and chemical stability typical of perfluorinated compounds; potential for static charge accumulation

Stability and Reactivity

Chemical Stability: Stable under standard storage conditions; prolonged exposure to heat or UV may cause slow decomposition or polymerization
Incompatible Materials: Strong acids, bases, oxidizers, and some reducing agents
Hazardous Decomposition Products: Combustion generates corrosive and toxic gases like hydrogen fluoride, carbon oxides, and acrylic decomposition products
Polymerization: Exposure to heat, light, or peroxides can initiate unwanted polymerization with heat evolution

Toxicological Information

Likely Routes of Exposure: Skin, eye, breathing in vapor
Potential Effects: Eye and skin contact often leads to short-term irritation; repeated exposure may bring sensitization for some people; inhaling high concentrations may cause headache or respiratory discomfort; ingestion not typical but presents a risk of gastrointestinal upset and fluorine release
Chronic Toxicity Data: No long-term studies for this specific molecule, existing data for related perfluorinated acrylates raise concerns over liver or kidney impact with chronic exposure; caution due to possible bioaccumulation like other fluorinated chemicals

Ecological Information

Environmental Fate: Perfluorinated portion is practically non-biodegradable and shows persistence in the environment; potential to accumulate in aquatic life
Aquatic Toxicity: Fluorinated acrylates can display toxicity to fish and aquatic invertebrates, exact EC50 values not often available in public literature
Special Remarks: Wastewater releases during production or usage can leave perfluorinated trace contaminants for decades; use closed-loop systems or recovery whenever possible

Disposal Considerations

Recommended Disposal Methods: Treat as hazardous waste; incinerate at a licensed facility equipped to handle fluorinated compounds and capture HF from exhaust; containers should not be reused in other applications
Special Precautions: Never pour into drains, sewers, or open ground; always label and segregate as perfluorinated chemical waste for collection
Preferred Practices: Centralized high-temperature incineration remains only reliable route, avoid landfill disposal due to persistence risk

Transport Information

UN Classification: May be subject to restrictions as environmentally hazardous substance if volumes shipped are significant
Labeling: Clearly marked as flammable liquid and environmental hazard per transport regulation conventions
Shipping Precautions: Keep containers sealed, upright, and protected from impact or high heat during transport; emergency response information on file during movement of bulk quantities

Regulatory Information

Compliance: Handlers should check for inclusion in regulatory lists focused on perfluorinated substances; several regional authorities watch for PFOA- or PFOS-like structures and may place restrictions
Worker Protection: Occupational safety regulations for chemical handling, using PPE, and exposure monitoring apply to fluorinated acrylates; company-level Hazard Communications programs needed by law in most developed countries
Environmental Regulation: National and local limits on waste discharge and emissions of perfluorinated materials demand pre-treatment and reporting; periodic audits help document compliance and drive environmental controls
