Pentan-3-one is an organic ketone compound with the molecular formula C5H10O and CAS number 96-22-0. It belongs to the family of aliphatic ketones, featuring a carbonyl group (C=O) at the third carbon position of a five-carbon chain. With a molecular weight of 86.13 g/mol, this volatile organic compound is classified as a flammable liquid and poses specific health hazards requiring careful handling in industrial applications.

Pentan-3-one is a colorless liquid ketone with a characteristic sweet, acetone-like odor. It has moderate solubility in water and is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound exhibits typical ketone reactivity and has a relatively low boiling point, making it volatile at room temperature. Its chemical structure allows for various organic reactions including nucleophilic additions and condensation reactions.

Pentan-3-one serves primarily as an industrial solvent and chemical intermediate in organic synthesis. It is commonly used in the production of pharmaceuticals, agrochemicals, and specialty chemicals. The compound finds applications in paint and coating formulations, adhesive manufacturing, and as a reaction medium in various chemical processes. Its ketone functionality makes it valuable for producing other organic compounds through condensation and addition reactions in fine chemical synthesis.

Pentan-3-one requires careful handling due to its flammable nature and potential health effects. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and eliminate ignition sources in the work area. Handle containers gently to prevent spills and use grounding procedures when transferring the material. Work in well-ventilated areas or under fume hoods to minimize inhalation exposure.

Pentan-3-one must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly sealed and store in compatible materials such as stainless steel or appropriate plastic containers. Maintain storage temperatures below 25°C and ensure separation from strong oxidizing agents and incompatible materials. Use appropriate secondary containment and ensure storage areas are equipped with fire suppression systems and spill control measures.

In case of skin contact with pentan-3-one, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist or worsen after exposure.

Pentan-3-one disposal must comply with local, national, and European waste regulations as it is classified as hazardous waste. The material should be collected in appropriate containers and disposed of through licensed waste management companies specializing in organic solvent recovery or incineration. Never discharge into sewers, waterways, or soil. Consider solvent recovery options where economically feasible. Contaminated containers must also be treated as hazardous waste and disposed of accordingly.

Pentan-3-one is classified under ADR Class 3 (Flammable Liquids), Packing Group II, requiring specific transport regulations compliance. Containers must meet UN specification standards and display appropriate hazard labels and markings. Transport vehicles need proper placarding and drivers require ADR certification. The material must be secured to prevent movement and spillage during transit. Ensure transport documentation includes proper shipping names, hazard classes, and emergency response information as required by dangerous goods regulations.

Pentan-3-one is subject to European REACH regulation requiring registration for commercial use and falls under CLP classification with specific labeling requirements including 'Danger' signal word and GHS02/GHS07 pictograms. The compound is classified as Flam. Liq. 2 and STOT SE 3, requiring appropriate safety data sheets and hazard communication. It is not currently listed as an SVHC substance, but users must comply with occupational exposure limits and workplace safety regulations in their respective countries.
