phenylacetone

Phenylacetone, also known as 1-phenyl-2-propanone, is an organic ketone with the formula C9H10O. Its structure features a phenyl group attached to a methylene bridge adjacent to a methyl ketone, giving the arrangement Ph-CH2-CO-CH3. In legitimate chemical manufacture, it is used as an intermediate in the synthesis of pharmaceuticals and other fine chemicals; it is also recognized as a precursor in the illicit production of amphetamine-type stimulants, notably methamphetamine. Because of its role as a controlled precursor in many jurisdictions, its production, sale, and distribution are subject to regulatory controls and licensing requirements. Phenylacetone is typically handled as a hazardous material: it is flammable and may cause irritation or other health effects; standard laboratory and industrial safety practices are advised, including use of appropriate containment, ventilation, and disposal procedures.
