TCI C0625 4'-Chloroacetoacetanilide (CAS 101-92-8) is the para isomer of chloroacetoacetanilide and serves as a non-heterocyclic building block in organic synthesis. Its active methylene site couples readily with diazonium salts, making it a standard partner in azo dye and yellow pigment research. The β-ketoamide framework also supports condensation routes toward pyrazolone and related heterocyclic rings. AMI Scientific offers this TCI reagent in a 25 g pack that suits laboratory-scale experiments and comparative studies against the ortho isomer.
