Chemical Formula: C6H12
Other Names: 1-Pentene, 4-methyl-
Physical State: Colorless liquid or gas, depending on conditions
Odor: Mild, hydrocarbon-like
Use: Industrial applications, especially copolymers and specialty plastics
Classification: Flammable liquid and vapor
Health Hazards: Can irritate eyes, skin, and respiratory tract
Environmental Hazards: Toxic to aquatic life on release
Main Risks: Fire hazard, vapor inhalation, environmental contamination
Main Ingredient: 4-Methyl-1-pentene, typically high purity
Impurities: Other aliphatic hydrocarbons, in minor concentrations depending on synthesis route
Inhalation: Move to fresh air, breathe easy, oxygen if trouble continues
Skin Contact: Wash thoroughly with water and soap
Eye Contact: Rinse with plenty of water for several minutes
Ingestion: Rinse mouth, don’t induce vomiting, seek medical help if large amounts enter system
Suitable Extinguishing Media: Foam, dry chemical, CO2
Specific Hazards: Flammable vapors can form explosive mixtures with air
Firefighting Advice: Wear self-contained breathing apparatus, keep containers cool with water spray
Products of Combustion: Carbon monoxide, carbon dioxide, possibly other toxic fumes
Personal Precautions: Remove ignition sources, ventilate area, avoid skin and eye contact
Spill Cleanup: Absorb with inert material, collect in a chemical waste drum, wash area with water
Environmental Precautions: Prevent runoff into drains or waterways, report large spills to authorities
Handling: Use in well-ventilated spaces, keep away from open flames and sparks, avoid breathing vapors
Storage: Store containers tightly sealed, away from heat and incompatible materials, label containers clearly, keep in a cool, dry location
Engineering Controls: Adequate local exhaust ventilation
Protective Equipment: Chemical goggles, solvent-resistant gloves, long sleeves
Hygiene Measures: Wash hands after handling, avoid eating or smoking during work, shower after shift if exposed
Workplace Limits: Reference OSHA or relevant authorities for exposure limit guidelines; levels often not established specifically for 4-methyl-1-pentene, general hydrocarbon limits may apply
Appearance: Clear, colorless liquid
Odor: Mild, sweet, hydrocarbon
Boiling Point: Around 63–65°C
Melting Point: Below 0°C
Flash Point: Below room temperature, highly flammable
Solubility: Insoluble in water, mixes with many organic solvents
Vapor Pressure: Noticeably high at room temperature
Density: Lower than water
Molecular Weight: About 84.16 g/mol
Chemical Stability: Stable under normal conditions, degrades with heat or open flame
Conditions to Avoid: High temperatures, open flames, static electricity
Reactive With: Strong oxidizers
Hazardous Decomposition: Carbon monoxide, carbon dioxide, hydrocarbons
Routes of Exposure: Inhalation, skin contact, eye contact
Short-Term Effects: Eye, skin, and respiratory irritation
Long-Term Effects: Chronic exposure not fully studied; similar hydrocarbons can cause central nervous system effects
Animal Testing: Data limited, other alkenes in this class show low toxicity in small doses, higher exposure may risk nervous system effects
Acute Aquatic Toxicity: Harmful to aquatic organisms
Persistence and Degradability: Not readily biodegradable
Bioaccumulation: Can accumulate in aquatic environments
Mobility in Soil: May contaminate groundwater
Precaution: Avoid release into the environment, follow local guidance on chemical use near waterways
Waste Disposal: Collect in marked drums, pass to licensed chemical waste disposal
Disposal Restrictions: Never pour down the drain or natural waterway
Contaminated Packaging: Dispose according to chemical waste guidelines, don’t reuse containers for food or drink
UN Number: Transportation as a flammable liquid
Hazard Class: 3 (Flammable liquids)
Packing Group: II or III due to volatility
Special Precautions: Label containers, keep upright and securely fastened during transport, avoid storage with incompatible chemicals
GHS Classification: Flammable liquid, hazardous if inhaled
Reporting: Subject to regional environmental and workplace safety laws, labeling required under OSHA and similar agencies
Regulations: Flammability means it gets strict rules for handling, storage, and shipping, usually covered under broad hydrocarbon chemical controls
