Indication of Immediate Medical Attention: Persistent respiratory or digestive tract symptoms, severe eye irritation, difficulty breathing
Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam, water spray/mist
Unsuitable Media: Do not use high pressure water jet as this may spread fire
Specific Hazards: May produce carbon monoxide, carbon dioxide, and unidentified hydrocarbons in case of combustion
Protective Equipment: Full protective gear, self-contained breathing apparatus for large fires or unventilated spaces
Special Precautions: Remove containers from fire area if it can be done safely, cool exposed containers with water spray, prevent run-off into sewers and water courses
Flash Point: Approximately 230°C (method dependent)
Personal Precautions: Ventilate area, avoid inhaling vapors, use protective equipment to prevent skin and eye contact
Environmental Precautions: Prevent entry into drains, surface water, or soil, contain spill using sand, earth, or suitable inert absorbent material
Cleanup Methods: Absorb spillage with inert material, scoop up and place in proper waste disposal container, clean area with detergent and water, ventilate thoroughly
Large Spill: Evacuate non-essential personnel, notify authorities if environmental contamination or a large release occurs
Disposal: Refer to local regulations for chemical waste, avoid release to environment
Safe Handling: Avoid contact with skin, eyes, or clothing, do not breathe vapors or mists, handle in areas with adequate ventilation, wash hands after use
Storage Conditions: Keep tightly closed in original container in a cool, dry, and well-ventilated area, protect from direct sunlight and moisture, keep away from sources of ignition and incompatible materials such as oxidizers
Incompatible Materials: Strong oxidizing agents, acids
Other Precautions: Use only with proper grounding/bonding since static buildup may occur with bulk liquid transfer
Occupational Exposure Limits: No established exposure limit for this compound identified
Engineering Controls: Local exhaust ventilation or general room ventilation recommended in processing areas
Personal Protective Equipment:
Eye Protection: Safety glasses with side shields or chemical splash goggles
Skin Protection: Protective gloves (nitrile or similar), industrial workwear
Respiratory Protection: Not required under normal use, use approved respirator for dusty, aerosol, or poorly ventilated environments
Hygiene Measures: Do not eat, drink, or smoke while handling, change contaminated clothing, wash thoroughly after handling
Appearance: Oily liquid, near colorless to pale yellow

Solubility: Insoluble in water, soluble in alcohols and most organic solvents
Viscosity: High, similar to other fatty acid esters
Partition Coefficient (n-octanol/water): Log Pow >4 (estimated, based on structural analogs)
Chemical Stability: Stable at normal temperatures, not reactive with common materials
Conditions to Avoid: Excessive heat, open flame, strong sunlight, direct exposure to oxidizers or acids
Materials to Avoid: Strong oxidizing agents, strong acids
Hazardous Decomposition Products: Combustion may yield carbon oxides, low molecular weight hydrocarbons, possible trace organic acids
Hazardous Polymerization: Will not occur
Acute Toxicity: Not defined due to lack of acute toxicity data, based on structure anticipated to be of low toxicity by oral, dermal, or inhalation routes
Skin Corrosion/Irritation: May cause mild irritation in sensitive individuals
Serious Eye Damage/Irritation: May cause mild, reversible irritation upon direct contact
Respiratory Sensitization: Not expected, cases not reported
Skin Sensitization: Low potential, rare allergic reaction possible
Germ Cell Mutagenicity: No evidence or expectation of mutagenic effects
Carcinogenicity: Not classified as a carcinogen by IARC, ACGIH, NTP, or OSHA
Reproductive Toxicity: Unlikely based on data for related compounds
Specific Target Organ Toxicity: Not expected under customary handling
Aspiration Hazard: Not classified as an aspiration hazard
Toxicity to Aquatic Life: Low acute toxicity expected to fish, invertebrates, and algae based on structure and analog data
Persistence and Degradability: Readily biodegradable, breakdown by microorganisms will occur in soil and water
Bioaccumulation: Low potential due to molecular size and expected rapid biodegradation
Mobility in Soil: Low due to insolubility in water and adsorption to soil particles
Other Adverse Effects: Not anticipated, but large releases should be avoided to prevent surface film formation in water which can affect oxygen transfer
