Acetanilide(CAT: A000848) is an aromatic amide derived from aniline and acetic acid, featuring a benzene ring linked to an acetamido group. It appears as a white to slightly gray crystalline solid and serves as a key intermediate in organic synthesis, especially for the production of dyes, pharmaceuticals, and rubber accelerators. Historically used as an analgesic and antipyretic, its medical use has been largely replaced due to safety concerns. Acetanilide remains valuable in research and industrial chemistry as a precursor for sulfa drugs and as a stabilizer for hydrogen peroxide and cellulose esters. It is also used in melting point calibration.
