Pentan-2-one is an organic ketone with the molecular formula C5H10O and CAS number 107-87-9. It is a five-carbon ketone where the carbonyl group is located at the second carbon position. With a molecular weight of 86.13 g/mol, this compound is commonly known as methyl propyl ketone and belongs to the family of aliphatic ketones used in various industrial applications.

Pentan-2-one is a colorless liquid at room temperature with a characteristic fruity, acetone-like odor. It has a boiling point of approximately 102°C and a density of about 0.81 g/cm³. The compound is moderately soluble in water and miscible with most organic solvents including alcohols, ethers, and hydrocarbons. It is volatile and flammable, which influences its handling and storage requirements.

Pentan-2-one is primarily used as a solvent in industrial applications, particularly in paint and coating formulations, adhesives, and cleaning products. It serves as an extraction solvent in chemical processes and as an intermediate in organic synthesis. The compound is also utilized in the production of resins, pharmaceuticals, and specialty chemicals due to its excellent solvating properties for various organic compounds.

Pentan-2-one should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation to prevent vapor accumulation. Avoid ignition sources as the compound is flammable. Use non-sparking tools and ensure proper grounding of equipment. Wash hands thoroughly after handling and avoid skin and eye contact.

Pentan-2-one must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use tightly sealed containers made of compatible materials such as steel or aluminum. Keep away from strong oxidizing agents and acids which may cause incompatible reactions. Storage areas should be equipped with appropriate fire suppression systems and spill containment measures.

In case of skin contact with pentan-2-one, immediately remove contaminated clothing and wash the affected area with plenty of soap and water. For eye contact, rinse immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical help if breathing difficulties occur. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Pentan-2-one waste must be disposed of according to local and national hazardous waste regulations. It should not be discharged into sewers or the environment. Collect waste in appropriate containers for disposal by licensed waste management companies. Small quantities may be suitable for solvent recovery or incineration at authorized facilities. Always consult local environmental authorities for specific disposal requirements in your region.

Pentan-2-one is classified under ADR transport regulations as Class 3 (Flammable Liquids), Packing Group II. It must be transported in approved packaging and vehicles equipped for flammable materials. Proper shipping documentation, labeling, and placarding are required. Transport vehicles should have appropriate emergency equipment and drivers must hold valid ADR certification for dangerous goods transport.

Pentan-2-one is subject to standard REACH registration requirements in the European Union and must comply with CLP classification and labeling regulations. It is not currently listed as a Substance of Very High Concern (SVHC). Users must follow standard industrial chemical handling protocols and may need to provide safety data sheets to downstream users. Local workplace exposure limits may apply depending on jurisdiction.
