Chemical Name: 2-Methyl-3-Ethylpentane
Common Names: Branched alkane, C8H18
Appearance: Clear, colorless liquid
Odor: Mild, gasoline-like scent
Uses: Laboratory research, sometimes blending for fuel-related studies
Chemical Formula: C8H18
Main Hazards: Highly flammable liquid and vapor, serious fire risk, can cause dizziness or drowsiness when inhaled, skin and eye irritation risk
GHS Classification: Flammable liquid, Specific target organ toxicity
Labeling: Signal word “Danger”, pictograms for flammable and health hazard
Precautionary Statements: Keep away from heat, sparks, open flames, avoid breathing vapors, use in well-ventilated areas, wear protective gloves and eye gear
Active Ingredient: 2-Methyl-3-Ethylpentane
Purity: Typically very high in lab use (>98%)
Impurities: Trace levels of other C8 isomers possible
Inhalation: Remove to fresh air, seek medical advice if symptoms like headache or nausea develop
Skin Contact: Wash affected skin with soap, remove contaminated clothing
Eye Contact: Flush eyes gently with water for several minutes
Ingestion: Do not induce vomiting, rinse mouth, get medical help right away
Extinguishing Media: Dry chemical, carbon dioxide, foam, avoid using water jets
Special Hazards: Vapors form explosive mixtures with air, fire can produce hazardous gases
Protective Equipment: Use self-contained breathing apparatus, full protective gear
Advice for Firefighters: Approach from upwind if possible, cool containers with water spray to prevent rupture
Personal Precautions: Remove ignition sources, ventilate area, avoid inhaling vapors
Spill Response: Use non-sparking tools, absorb liquid with inert material, clean up using chemical-resistant gloves
Environmental Protection: Prevent entry into drains or surface waters, contain spill as much as possible
Handling: Ground and bond containers when transferring, keep away from sources of ignition, wear chemical-resistant gloves and eye protection, minimize splashing or vapor generation
Storage: Store in tightly closed containers, in cool, well-ventilated spaces away from incompatible materials like strong oxidizers, keep out of reach of children and untrained persons
Ventilation: Work in a hood or well-ventilated environment
Personal Protection: Use nitrile or neoprene gloves, safety goggles, lab coat
Respiratory Protection: Use a chemical cartridge respirator if ventilation is insufficient
Engineering Controls: Use spark-proof equipment and explosion-proof electrical fixtures, install exhaust fans for confined spaces
Boiling Point: Around 117°C
Melting Point: Not well-documented for uncommon isomers
Vapor Pressure: Likely moderate, typical of medium-chain hydrocarbons
Density: Less than water, tends to float
Solubility in Water: Practically insoluble, but mixes well with organic solvents
Appearance: Clear, mobile liquid
Odor: Gasoline-like, not overpowering
Chemical Stability: Stable under ordinary conditions
Reactivity: Can react with strong oxidizers to cause fire or explosion
Incompatible Materials: Strong acids and bases, oxidizing agents
Hazardous Decomposition: Produces carbon monoxide and dioxide under fire conditions, along with potentially irritating hydrocarbons
Likely Routes of Exposure: Inhalation, skin contact, accidental ingestion
Health Effects: Vapors may cause headaches, dizziness, respiratory irritation, prolonged skin contact can cause dryness or cracking, accidental ingestion brings risk of chemical pneumonia if aspirated
Chronic Hazards: Repeated exposures may impact central nervous system, no strong data suggesting carcinogenicity or mutagenicity among standard alkane isomers
Aquatic Toxicity: Toxic to fish and aquatic invertebrates at high concentrations, forms surface films that can interfere with oxygen transfer in water
Persistence: Degrades slowly, can linger in the environment
Mobility: Spreads over water surfaces, slowly evaporates into air
Other Concerns: Not likely to bioaccumulate significantly, but spills should be treated as hazardous to sensitive ecosystems
Waste Disposal: Collect as hazardous waste, send to chemical incinerator or regulated disposal facility, do not pour down drains
Environmental Precautions: Check local and national regulations, avoid landfill or uncontrolled burning
Hazard Class: Flammable liquid
Packing Group: Usually Group II or III for medium volatility hydrocarbons
Transport Labeling: Marks for “Flammable Liquid”, suitable container labeling for shipment
Spill Response in Transit: Isolate and ventilate, notify authorities if required
Labeling Requirements: Label as flammable, include health hazard warnings per GHS or OSHA HCS
Regulatory Status: Addressed under general hydrocarbon handling laws, not featured as a controlled substance
Worker Protection: Meets OSHA, EU REACH, and similar worker safety guidelines, proper labeling and training required
Reporting Obligations: Follow spill and exposure reporting rules, especially near water or for public health protection
