Chemical Synonyms: 3-methylbutyl butyrate, Isopentyl butyrate
Relevant Identifiers: EC No: 203-392-4
Inhalation: Remove person to fresh air, provide oxygen if breathing is difficult, seek medical attention if symptoms persist
Skin Contact: Wash area with soap and plenty of water, remove contaminated clothing, consult a physician if irritation develops
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, keep eyelids open, seek medical advice if sensation continues
Ingestion: Rinse mouth with water, do not induce vomiting, get medical attention right away if large quantity is swallowed or symptoms arise
Suitable Extinguishing Media: Foam, carbon dioxide, dry chemical, water spray in fog form
Unsuitable Media: Direct water jet
Combustion Hazards: Releases irritating and toxic fumes (including carbon monoxide, carbon dioxide) during combustion
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Special Procedures: Avoid inhaling vapors; cool exposed containers with water spray to prevent pressure build-up and potential explosion
Personal Precautions: Evacuate unnecessary personnel from area, wear protective gloves and eye protection, avoid breathing vapors
Spill Cleanup: Use non-combustible absorbent material (sand, earth, vermiculite), shovel into containers for disposal, ventilate confined areas
Environmental Precautions: Prevent from entering sewers, surface or groundwater; notify authorities if large spills reach water bodies
Safe Handling: Avoid exposure, do not breathe vapors, use only in well-ventilated areas, keep away from heat, sparks, open flames
Storage Requirements: Store in tightly closed original container in a cool, dry, well-ventilated place, away from incompatible substances such as strong oxidizers
Incompatible Materials: Strong acids, bases, oxidizing agents
Other Precautions: Ground/bond container and receiving equipment, avoid prolonged or repeated exposure
Engineering Controls: Local exhaust ventilation, mechanical ventilation to control airborne levels
Personal Protection: Nitrile or neoprene gloves, safety goggles, lab coats or appropriate protective clothing
Respiratory Protection: Approved respirators in case of high vapor concentration or accidental release
Hygiene Measures: Wash hands thoroughly after use, avoid contact with skin, eyes, and clothing, do not eat, drink, or smoke during use

Acute Toxicity: Low toxicity expected based on available data for similar esters; may cause mild skin or respiratory irritation
Skin Sensitization: May cause irritation on prolonged or repeated exposure
Eye Effects: Direct contact may cause stinging, redness, or watering
Inhalation Risks: High vapor concentrations may cause headache, drowsiness, or respiratory discomfort
Ingestion Risks: May cause gastric upset, nausea, vomiting after swallowing significant quantities
Ecotoxicity: Toxic to aquatic life on acute exposure; longer-term impacts possible, especially if spilled in large quantities
Persistence: Likely to biodegrade under aerobic conditions, slower in anaerobic environments
Bioaccumulation: Not considered to have significant bioaccumulation potential
Mobility: Migrates in soil, can contaminate water sources if discharged carelessly
Waste Treatment: Incineration under controlled conditions is preferred, follow national or local guidelines for chemical wastes
Packaging Disposal: Rinse containers thoroughly before recycling or discarding, never discard in regular landfill or natural environment
Environmental Precaution: Avoid release to water bodies or soil, always keep waste segregated from incompatible substances
