Acetoacetanilide
Acetoacetanilide is an organic compound with the formula CH3CCH2CNHC6H5. It is the acetoacetamide derivative of aniline. It is a white solid that is poorly soluble in water. It and many related compounds are used in the production of organic pigments called arylide yellows.Acetoacetanilide is prepared by acetoacetylation of aniline using diketene.
To make the dyes, acetoacetanilides are coupled to diazonium salts, "azo coupling".
