2Phenylpropanone

2-Phenylpropanone, also known as benzyl methyl ketone or phenylacetone, is an organic compound with the chemical formula C9H10O. It is a colorless to pale yellow oily liquid with a sweet, floral odor. The molecule consists of a phenyl group attached to a propanone backbone at the second carbon atom.

This compound is primarily used as a precursor in the synthesis of various chemicals, including pharmaceuticals and perfumes. Historically, it has also been utilized in the illicit manufacture of amphetamines and methamphetamines, leading to its controlled status in many countries. Due to its potential for misuse, its production, distribution, and sale are often subject to strict regulations.

2-Phenylpropanone can be synthesized through several chemical reactions, including the Friedel-Crafts acylation of benzene with propionyl chloride or the oxidation of 2-phenylpropanol. It is soluble in most organic solvents but sparingly soluble in water. Its chemical properties make it a reactive intermediate in organic chemistry.
