Name: 4-Methyl-2-pentanol
Synonyms: Methyl isobutyl carbinol, MIBC
Chemical Formula: C6H14O
CAS Number: 108-11-2
Appearance: Colorless liquid
Odor: Faint, sweet alcohol scent
Boiling Point: 131–132°C
Classification: Flammable, irritant
Hazard Symbols: Flammable symbol, irritant symbol
Primary Risks: Eye and skin irritation, central nervous system effects from inhalation, fire risk from vapor
Acute Effects: Dizziness, headache, nausea, respiratory tract irritation
Chronic Exposure: Possible liver and kidney effects, but more research is always needed for long-term outcomes
Main Component: 4-Methyl-2-pentanol (usually over 99%)
Impurities: Trace byproducts from manufacturing, such as minor alcohols or hydrocarbons
Inhalation: Move person to fresh air, keep at rest, watch for breathing difficulty, seek medical advice if symptoms persist
Skin Contact: Wash affected area with soap and water, remove contaminated clothing
Eye Contact: Rinse eyes with water for several minutes, lift eyelids occasionally, check for irritation
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical help if a large amount is swallowed
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide
Specific Hazards: Vapors can form explosive mixtures with air, may emit toxic fumes under fire conditions
Protective Equipment: Full protective gear, self-contained breathing apparatus
Personal Precautions: Avoid eye and skin contact, ensure good ventilation, keep away from ignition sources
Cleanup Methods: Use proper absorbent, collect spillage in sealable containers, wash residue from small spills with plenty of water
Environmental Impact: Prevent further leakage if safe, do not allow entry into drains, surface water, or soil
Safe Handling: Use explosion-proof equipment, avoid breathing vapors, maintain good housekeeping
Storage Conditions: Store in tightly closed containers, keep in a cool, well-ventilated space, segregate from oxidizers and acids
Ventilation: Local exhaust and general ventilation help keep vapor levels low
Personal Protection: Use chemical-resistant gloves, safety glasses, lab coat
Respiratory Protection: Use respirators if ventilation is inadequate
Workplace Monitoring: Regular air monitoring for vapor levels supports a safe environment
State: Liquid
Odor: Mild, alcohol-like
Boiling Point: 131–132°C
Melting Point: -90°C
Flash Point: Around 44°C
Vapor Pressure: Moderate at room temperature
Solubility: Slightly soluble in water, readily dissolves in most organic solvents
Specific Gravity: About 0.81 at 20°C
Chemical Stability: Stable under recommended conditions
Reactivity: May react violently with strong oxidizers, acids
Decomposition: Heating may release toxic fumes, including carbon monoxide and carbon dioxide
Acute Toxicity: Oral LD50 in rats is several grams per kilogram, so relatively low toxicity but still a hazard at high doses
Exposure Routes: Inhalation, ingestion, skin and eye contact
Symptoms: Dizziness, drowsiness, narcosis at high concentrations, irritation to eyes/skin
Long-term Exposure: Repeated inhalation may depress the central nervous system; metallic taste, nausea with acute overexposure
Mobility: Can move through soil to groundwater due to low absorption
Persistence: Expected to biodegrade under environmental conditions, but spills can cause harm
Toxicity to Aquatic Life: Moderate to high toxicity for some water organisms,
Bioaccumulation Potential: Low
Treatment: Collect and send to licensed waste handler
Waste Disposal: Follow all local, regional, and national requirements for chemical waste
Incineration: Suitable in a chemical incinerator with afterburner and scrubber
Hazard Class: Flammable liquid
Packaging: Use approved containers with secure closures
Labeling: Flammable liquid label required
Precautions: Handle with care, avoid impacts or heat during transit
GHS Classification: Flammable liquid, eye irritation hazard, specific target organ toxicity
Workplace Regulations: Subject to OSHA and similar bodies' workplace air monitoring and exposure limits
Environmental Rules: Restrictions may exist for disposal or spillage, reporting requirements often apply under local statutes
Banned Uses: None broadly reported, but standard use restrictions apply in sensitive settings like food manufacturing
