5-Chloro-2-nitroaniline (CAS 1635-61-6) from TCI is a versatile non-heterocyclic building block bearing amino, nitro, and chloro substituents on a single aromatic ring. Its aromatic amine is readily diazotised for azo dye synthesis, while reduction of the nitro group opens routes toward benzimidazoles and related heterocycles. The aryl chloride offers an additional handle for metal-catalysed cross-coupling chemistry. AMI Scientific supplies this reagent in 25 g and 250 g pack sizes for research and development laboratories.
