Name: 2,4-Dimethylpentane Synonyms: Diisobutylmethane, Isooctane isomer Chemical Formula: C7H16 CAS Number: 108-08-7 Appearance: Colorless liquid with a mild petroleum-like odor Common Uses: Solvent, research chemical, octane booster in gasoline Boiling Point: Approximately 99°C Molecular Weight: 100.2 g/mol Smell: Faint, resembles gasoline Not usually encountered outside of laboratories and fuel processing plants
Main Dangers: Flammable liquid and vapor Potential Health Risks: May cause dizziness, headaches, nausea if inhaled Skin Contact: Can provoke mild irritation or dryness after prolonged exposure Eye Contact: May result in minor irritation Inhalation: High concentrations may lead to central nervous system effects such as confusion and drowsiness Long-Term Exposure: Chronic risks remain unclear due to limited human data Environmental Harm: May threaten aquatic life upon release into waterways Flammability: High—keep away from sparks, flames, static discharge Explosion Risk: Vapor mixes with air can ignite easily
Main Ingredient: 2,4-Dimethylpentane, purity often above 95% Possible Trace Impurities: Other branched-chain alkanes from manufacturing No common additives in lab-grade or industry samples
Inhalation: Bring affected person into fresh air immediately Skin Contact: Wash off with soap and plenty of running water Eye Contact: Rinse gently with plenty of water for several minutes Ingestion: Rinse mouth if conscious; do not induce vomiting Obtain medical attention if symptoms persist or significant exposure occurred Flush contaminated clothing before reuse
Suitable Extinguishers: Foam, dry chemical, carbon dioxide Unsuitable Media: Water streams may spread flammable liquid Special Hazards: Vapors heavier than air, can travel to ignition sources Protection for Firefighters: Full protective bunker gear, self-contained breathing apparatus Runoff water from fire control may be flammable, needs containment
Isolate spill area promptly; ventilate space Eliminate all ignition sources immediately Wear gloves, eye protection, and organic vapor respirators if clean-up involves liquid handling Collect spilled liquid with absorbent material like sand or commercial pads Dispose collected waste according to local hazardous waste rules Prevent entry into sewers, waterways, or soil
Keep containers tightly closed in a cool, well-ventilated space Store away from open flames, hot surfaces, or direct sunlight Ground and bond containers to avoid static discharge Avoid breathing vapors or prolonged skin contact No smoking in areas where the liquid is used or stored Label storage spaces clearly; restrict access to authorized handlers
Engineered ventilation such as fume hoods is often necessary Wear chemical splash goggles and gloves made from compatible materials Use flame-resistant lab coats or clothing Proper respiratory protection when vapor concentrations creep above safe background levels Wash hands after handling and before eating or drinking Employ eye wash stations and safety showers in close proximity No food, drink, or tobacco use while working with the substance
Appearance: Clear, colorless liquid Odor: Gasoline-like, mild intensity Melting Point: Data not widely recorded for this compound Boiling Point: Near 99°C Vapor Pressure: Around 50 mmHg at 20°C Solubility: Insoluble in water, soluble in organic solvents Density: Approximately 0.69 g/cm³ Flash Point: Around -7°C, making it highly flammable Evaporation Rate: Comparable to other lighter alkanes Vapor heavier than air, accumulates in low spots
Stable in sealed containers under basic storage conditions Reacts dangerously with strong oxidizers (e.g., peroxides, chlorine) Sensitive to heat, flames, sparks, or static electricity Forms explosive mixtures in air at moderate concentrations No known hazardous polymerization Decomposition may create hazardous gases like carbon monoxide and carbon dioxide if burned Protect from mechanical shock and avoid rough handling
Acute Toxicity: No reliable reports of life-threatening poisoning from small exposures Inhalation Effects: May cause headaches, drowsiness, or narcosis above safe levels Skin Sensitization: Not commonly reported, but can irritate after repeat contact Eye Effects: Mild, transient irritation Chronic Effects: Data limited on long-term or reproductive toxicity Carcinogenicity: Not classified by major international agencies Intentional misuse—such as inhalant abuse—can result in serious health problems or death
Rapidly evaporates from open surfaces, limiting direct aquatic exposure Toxic to aquatic organisms at high concentrations Breaks down slowly in soil and water Unlikely to bioaccumulate significantly based on chemical structure Managing spills by containment and rapid clean-up helps avoid environmental release Not classified as persistent organic pollutant
Never pour down the drain or discard with everyday garbage Collect and dispose using licensed hazardous waste services Rinsate and contaminated materials require special handling Incineration at approved sites is the most reliable destruction route Follow national and local rules for disposal; many restrict open burning or landfill Triple-rinse empty containers or puncture before disposal
Classified as flammable liquid by most transport authorities Pack in approved flammable liquid containers Label with relevant flammable hazard class symbol Requires shipping papers describing the substance by its full chemical name Keep away from heat, friction, or impact during transit Check for travel restrictions—airlines and railroads often ban transport of such chemicals by passengers
Listed under major regimens as a hazardous chemical due to its flammability Subject to reporting and control requirements in many regions Threshold quantities may trigger reporting or storage requirements Occupational exposure limits set by agencies such as OSHA or ACGIH Workers must receive training on chemical hazards and safe handling practices Proper labeling and safety signage mandated at all handling or storage sites Compliance with fire codes, chemical storage regulations, and hazardous materials standards protects people and property
