Chemical Identity: Cis-11-Eicosenoate Methyl Ester
Concentration: ≥98% (typical for laboratory grade)
Impurities: Small amounts of related fatty acid methyl esters possible
Other Components: No additives or stabilizers present
Inhalation: Move affected person into fresh air. Keep at rest and provide comfortable breathing conditions. If symptoms persist, seek medical care.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with plenty of water and soap. Pay attention to any signs of irritation.
Eye Contact: Rinse cautiously with clean water for several minutes. Remove contact lenses if present. If discomfort continues, consult a physician.
Ingestion: Rinse mouth with water, do not induce vomiting. Call a medical professional for direction if any discomfort or symptoms arise.
Most Important Symptoms: Light skin or eye irritation, no severe acute effects documented
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Unsuitable Extinguishing Media: Direct stream of water can spread the fire
Special Hazards: Combustible liquid, vapors may form explosive mixtures with air if heated significantly. Decomposition can produce carbon oxides.
Protective Equipment for Firefighters: Wear full protective clothing and self-contained breathing apparatus
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, trace organic fumes
Advice: Remove non-involved personnel, avoid inhaling combustion products, contain runoff to prevent environmental contamination
Personal Precautions: Use appropriate personal protective equipment such as gloves and goggles, avoid breathing vapors, ensure adequate ventilation
Environmental Precautions: Prevent entry into sewers, soil, or waterways as much as possible, notify authorities in case of large spills
Clean-Up Methods: Absorb with inert material such as sand or earth, scoop into containers for proper disposal, clean area with detergent and water to remove residues
Safe Handling: Use in a well-ventilated area, keep away from heat/sparks/flame, avoid direct contact with skin and eyes
Storage: Store in a tightly sealed container in a cool, dry environment out of direct sunlight. Segregate from oxidizing agents and foodstuffs.
Incompatibilities: Strong oxidizing agents, strong acids or alkalis can break down the ester under extreme conditions
Hygiene Practices: Wash hands after handling, do not eat, drink, or smoke during use
Engineering Controls: Use local exhaust or general ventilation if substantial vapors are expected, minimize aerosol generation
Personal Protection: Wear safety goggles, laboratory gloves, and lab coat; in case of insufficient ventilation or risk of inhaling mist, use an approved respirator
Exposure Limits: No government or industry exposure limits established for this specific compound
Workplace Practices: Handle containers carefully, clean up spills promptly, maintain good housekeeping in work areas

Decomposition Products: Carbon monoxide, carbon dioxide, potentially irritating organic fumes
Acute Toxicity: No acute toxicity data available for humans or animals
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Symptoms: May cause mild skin or eye irritation, unlikely to cause serious effects from accidental exposure
Chronic Effects: No known sensitization or chronic health effects, not classified as a carcinogen
Mutagenicity/Carcinogenicity: No data indicating mutagenic or carcinogenic effects
Reproductive Toxicity: Not established for this ester; structurally similar fatty acid derivatives show low toxicity
Environmental Behavior: Not readily biodegradable, high persistence due to lipophilicity
Bioaccumulation Potential: High due to fat solubility
Aquatic Toxicity: No established LC50 or EC50 for aquatic organisms; risk increases if released in large quantities into water
Mobility in Soil: Adsorbs strongly to soil particles, limited mobility
Other Ecological Effects: Avoid uncontrolled release; long-chain esters can persist in some environments
