Hazard Statements: Highly flammable liquid and vapor, causes skin irritation, may cause drowsiness or dizziness, toxic to aquatic life with long-lasting effects
Precautionary Statements: Keep away from heat and open flames, avoid inhaling vapors, use only outdoors or in well-ventilated areas, wear suitable protective clothing, avoid release into the environment
Component: N-Butylbenzene
Concentration: ≥99%
Molecular Weight: 134.22 g/mol
Impurities: Trace levels of closely related alkylbenzenes, if any, kept under 1% total
Inhalation: Remove to fresh air immediately, keep individual at rest and provide oxygen if breathing is difficult; seek medical attention if symptoms such as headache, dizziness, or nausea develop
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water and mild soap for at least 15 minutes; seek medical advice if irritation persists
Eye Contact: Rinse immediately with gentle stream of water for at least 15 minutes, keeping eyelids open; obtain medical attention if irritation or pain continues
Ingestion: Rinse mouth without inducing vomiting; never give anything by mouth to an unconscious person; contact a physician or local poison control center promptly
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, foam
Unsuitable Media: Avoid direct water stream, which may spread the burning material
Fire Hazards: Vapors may form explosive mixtures with air, container may rupture if heated
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing, cool fire-exposed containers with water spray from a safe distance
Hazardous Combustion Products: Toxic fumes including carbon monoxide and carbon dioxide released on burning
Personal Precautions: Evacuate unprotected personnel from area, ventilate area well, remove all sources of ignition
Protective Equipment: Wear chemical splash goggles, gloves, and protective clothing
Spill Containment: Prevent further leakage or spillage, contain with inert absorbent material (sand, earth, vermiculite)
Cleanup Methods: Collect residues in suitable closed containers for disposal; wash spill site after material pickup is complete, avoid direct contact with soil and waterways
Handling: Work in well-ventilated areas or use local exhaust, avoid breathing vapors and contact with skin or eyes, keep away from ignition sources, use spark-proof tools, ground containers during transfer
Storage: Store in tightly sealed containers made of compatible materials, in a cool, dry, well-ventilated place, away from heat, sparks, and strong oxidizing agents
Incompatible Materials: Strong acids, bases, oxidizers
Exposure Limits: No specific regulatory limits, but minimize vapors as low as reasonably achievable
Control Measures: Use fume hoods or extraction fans if possible, monitor vapor levels regularly
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), splash-proof safety goggles, flame-retardant lab coat, and, during large-scale use, a certified respirator
Hygiene Measures: Do not eat, drink, or smoke during use; wash hands after handling and before breaks
Physical State: Clear, colorless liquid

Viscosity: About 1.1 mPa·s
Partition Coefficient, n-octanol/water (log Kow): 4.1
Autoignition Temperature: 430 °C
Stability: Stable under recommended handling and storage conditions
Reactive Conditions: Exposure to heat, flame, sparks; contact with oxidizing agents
Incompatibilities: Strong oxidizers, acids
Hazardous Decomposition Products: Produces carbon oxides, irritating vapors, and volatile organic compounds upon decomposition
Polymerization: No hazardous polymerization expected under normal conditions
Acute Toxicity: Oral LD50 (rat): >3000 mg/kg; inhalation and dermal toxicity expected low but data limited
Irritation: Causes moderate skin and eye irritation
Sensitization: No data suggests skin sensitizer
Chronic Effects: Prolonged or repeated exposure might lead to nervous system effects, headaches, and skin dryness
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Other Health Effects: May cause drowsiness, dizziness, and, in high concentrations, CNS depression
Environmental Impact: Toxic to aquatic life, particularly fish and invertebrates; may cause long-term adverse effects in aquatics
Degradability: Not readily biodegradable, persistent in soil and water
Bioaccumulation: Has potential to bioaccumulate due to high log Kow
Mobility: Low solubility may lead to slow migration in environment
Waste Treatment Methods: Dispose of in accordance with local, regional, and national regulations through hazardous waste handler; incineration preferred in appropriate facility
Contaminated Packaging: Triple rinse containers, then puncture and send to permitted waste handler
Precautions: Do not discharge to drains, soil, or aquatic environment, minimize releases wherever possible
