Inhalation: Move person to fresh air, keep comfortable, seek medical attention for respiratory irritation, headache, or dizziness
Skin Contact: Remove contaminated clothing, wash skin under running water for several minutes, consult physician if irritation persists
Eye Contact: Rinse eyes cautiously with water for at least 15 minutes, remove contact lenses if present, continue rinsing, contact an eye specialist if irritation develops
Ingestion: Rinse mouth, call for medical advice, avoid inducing vomiting unless instructed by a medical professional
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide for small fires; water spray for larger volumes; do not use solid water stream
Specific Hazards: Vapors may form explosive mixtures with air; burning releases toxic gases including carbon monoxide and carbon dioxide
Protective Equipment: Firefighters should wear self-contained breathing equipment with full protective gear
Fire Fighting Instructions: Evacuate area, cool containers exposed to fire, prevent runoff from reaching waterways
Personal Precautions: Isolate area, ventilate space, avoid breathing vapor, use protective gloves and goggles
Spill Cleanup: Absorb spill with non-combustible material, transfer to a closed container, wash spill area with detergent and water
Environmental Precautions: Prevent product from entering drains, soil, or waterways, contain runoff using sand or earth
Handling: Work in a well-ventilated place, ground containers when transferring, keep away from ignition sources, avoid inhalation or direct skin contact
Storage: Store in tightly sealed original containers in a cool, dry, and well-ventilated space, keep away from sources of heat and direct sunlight, note national legal requirements
Incompatible Materials: Avoid oxidizing agents, nitric acid, and strong acids or bases
Occupational Exposure Limits: No specific OSHA or ACGIH limits; follow general exposure guidelines for organic solvents
Engineering Controls: Use localized exhaust ventilation or process enclosure, utilize fume hood for laboratory settings
Personal Protective Equipment: Use chemical-resistant gloves (nitrile, neoprene), splash goggles, lab coat or chemical apron, respirator under insufficient ventilation
Hygiene Practices: Wash hands after handling, remove contaminated clothing before eating or leaving the work area
Appearance: Colorless liquid, clear
Odor: Fruity, mild ester-like smell
Odor Threshold: Not determined

Flash Point: 38–40°C (closed cup)
Evaporation Rate: Moderate
Flammability: Flammable liquid and vapor
Vapor Pressure: 3.4 mm Hg at 20°C
Vapor Density: 4.5 (Air = 1)
Relative Density: 0.87 g/cm³
Solubility: Miscible with organic solvents, low solubility in water
Partition Coefficient (n-octanol/water): 2.1
Auto-Ignition Temperature: 425°C
Decomposition Temperature: Not specified
Chemical Stability: Stable at normal temperatures and pressures under recommended storage conditions
Reactivity: Reacts with oxidizing agents, acids, and bases; forms flammable vapors with air
Hazardous Decomposition: Releases carbon dioxide, carbon monoxide, and acrid smoke if burned or decomposed
Polymerization Risk: Not known to polymerize under normal conditions
Routes of Entry: Inhalation, dermal, eye, ingestion
Acute Effects: Inhalation may result in headache, dizziness, drowsiness; eye contact causes significant irritation; skin contact may produce moderate irritation after prolonged or repeated exposure
Chronic Exposure: May cause mild skin dryness or cracking with repeated handling; no evidence for significant organ toxicity or carcinogenicity found in animal studies
LD50 (Oral, rat): 5685 mg/kg
LD50 (Dermal, rabbit): > 5000 mg/kg
LC50 (Inhalation, rat, 4h): > 21 mg/L
Additional Data: No mutations or reproductive toxicity identified in available studies
Aquatic Toxicity: Moderate hazard to aquatic life (LC50 (fish, 96h): approximately 100 mg/L)
Persistence and Degradability: Readily biodegradable in water and soil under aerobic conditions
Bioaccumulative Potential: Low potential for bioaccumulation; partition coefficient suggests moderate movement into aquatic organisms, but rapid breakdown limits this risk
Mobility in Soil: High mobility expected, product may leach into water table if spilled
Other Adverse Effects: No significant ozone depletion or greenhouse gas effects
Waste Disposal: Collect waste in labeled, sealed containers for chemical waste disposal; do not pour down drains or into the environment
Incineration: Use a licensed facility with appropriate pollution controls
Container Disposal: Empty drums should be triple rinsed, punctured, and sent to a permitted recycling or waste management site
Regulatory Notes: Always check local, regional, and national environmental disposal regulations prior to disposal
