Acetoacetamide is an organic compound with the formula CH₃COCH₂CONH₂. It is the amide of acetoacetic acid. It is produced by treating diketene with aqueous ammonia^[1]

It results from degradation of the sweetener acesulfame potassium.^[2]

Related compounds

Acetoacetanilide (CH₃COCH₂CONH₂) is the N-phenyl derivative of acetoacetamide. It is also prepared from diketene.^[3] It and various derivatives are used in the production of organic pigments called arylide yellows, one example being Pigment Yellow 74. Many analogues have been prepared.^[4] To make the dyes, acetoacetanilides are coupled to diazonium salts, "azo coupling".^[5]
