A white, odorless powder that has a burning taste. Acetanilide is produced from aniline using acetic acid. The shiny, leaflet crystals are stable in air. Acetanilide was used in the 19th century to treat fever and headaches but was discontinued because of toxic side effects. It is still used in the manufacture of medicines and dyes, as an accelerator for rubber vulcanization, as a stabilizer for cellulose ester dopes and lacquers, and as a synthetic camphor.
