4-methylpentan-2-one

4-methylpentan-2-one is an organic ketone with the molecular formula C6H12O and CAS number 108-10-1. This chemical compound has a molecular weight of 100.16 g/mol and belongs to the family of methyl ketones. It is classified as a flammable liquid with carcinogenic properties and represents significant health hazards requiring careful handling in industrial applications.

4-methylpentan-2-one is a colorless liquid ketone with a characteristic sweet, fruity odor typical of ketones. It has moderate volatility at room temperature and is partially soluble in water while being fully miscible with most organic solvents like alcohols and ethers. The compound exhibits typical ketone reactivity and maintains stability under normal storage conditions.

4-methylpentan-2-one serves primarily as a solvent in industrial applications and as an intermediate in organic synthesis. It is commonly used in the production of pharmaceuticals, agrochemicals, and specialty chemicals. The compound also finds applications in the formulation of coatings, adhesives, and cleaning products where its ketone properties provide effective solvency for various organic materials.

4-methylpentan-2-one requires strict safety protocols due to its flammable and carcinogenic nature. Workers must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Handle only in well-ventilated areas or under fume extraction, avoid all ignition sources, and ensure emergency shower and eyewash stations are readily accessible.

4-methylpentan-2-one must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use only approved containers resistant to ketones and ensure proper grounding to prevent static electricity buildup. Store separately from oxidizing agents, strong acids, and bases to prevent incompatible reactions that could lead to fire or explosion.

4-methylpentan-2-one exposure requires immediate action depending on contact type. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention.

4-methylpentan-2-one disposal must comply with local and European waste regulations as it is classified as hazardous waste. The compound should be collected in appropriate containers and disposed of through licensed hazardous waste disposal facilities. Incineration at high temperatures in specialized facilities is typically the preferred disposal method. Never discharge into sewers or the environment.

4-methylpentan-2-one is classified under ADR as Class 3 (Flammable Liquids), Packing Group II, indicating moderate danger during transport. It must be shipped in UN-approved packaging with proper hazard labels and documentation. Vehicles must be equipped with appropriate fire extinguishers and drivers must have ADR training certificates for transporting flammable liquids.

4-methylpentan-2-one is regulated under European REACH and CLP regulations due to its carcinogenic classification (Carc. 2). While not currently listed as an SVHC substance, its Category 2 carcinogen status requires specific risk management measures and safety data sheet provisions. Users must comply with occupational exposure limits and implement appropriate risk management strategies.
