This chemical substance has a molecular weight of 100.16 g/mol and belongs to the family of aliphatic ketones. It is classified as a flammable liquid with potential carcinogenic properties and moderate toxicity. The compound is characterized by its ketone functional group positioned at the second carbon of a branched pentane chain.

4-methylpentan-2-one is a colorless to pale yellow liquid at room temperature with a characteristic ketone odor. As an organic solvent, it exhibits moderate volatility and is partially miscible with water while being fully soluble in most organic solvents. The compound has a relatively low molecular weight of 100.16 g/mol, contributing to its volatile nature and solvent properties typical of ketones.

4-methylpentan-2-one is primarily used as an industrial solvent in various chemical processes and formulations. It serves as an extraction solvent, cleaning agent, and intermediate in organic synthesis. The compound finds applications in the production of coatings, adhesives, and specialty chemicals. Its ketone structure makes it valuable for dissolving resins, polymers, and other organic materials in industrial manufacturing processes.

4-methylpentan-2-one requires careful handling due to its flammable nature and potential health hazards. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection when adequate ventilation is not available. Work should be conducted in well-ventilated areas away from ignition sources. Given its Acute Tox. 4 and Carc. 2 classifications, minimize skin contact and inhalation exposure through proper engineering controls and safe work practices.

4-methylpentan-2-one must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its Flam. Liq. 2 classification. Use appropriate containers made of compatible materials and ensure proper grounding to prevent static electricity buildup. Storage areas should be equipped with fire suppression systems and spill containment measures. Keep containers tightly sealed and store away from incompatible materials such as strong oxidizing agents.

4-methylpentan-2-one contact requires immediate action depending on exposure route. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek medical attention. Always consult emergency services for serious exposures.

4-methylpentan-2-one disposal must comply with local and European waste regulations as a hazardous chemical waste. The substance cannot be disposed of in regular waste streams due to its flammable and potentially carcinogenic properties. Arrange disposal through licensed hazardous waste contractors who can handle flammable organic solvents. Ensure proper waste classification, packaging, and documentation according to waste framework directive requirements. Never pour down drains or release into the environment.

4-methylpentan-2-one is classified under ADR Class 3 (Flammable Liquids), Packing Group II, requiring specific transport regulations compliance. Packages must meet UN specifications for flammable liquids and display appropriate hazard labels and markings. Transport vehicles need proper ventilation, fire extinguishing equipment, and trained drivers with ADR certification. Shipping documents must include proper shipping names, UN numbers, and emergency response information according to dangerous goods transportation regulations.

4-methylpentan-2-one is regulated under European REACH and CLP regulations requiring registration, classification, and labeling compliance. The substance carries mandatory hazard classifications including Flam. Liq. 2, Carc. 2, and Acute Tox. 4, requiring specific safety data sheets and hazard communication. While not currently listed as SVHC, its carcinogenic classification subjects it to potential future restrictions. Industrial users must ensure REACH registration compliance and implement appropriate risk management measures.
