TCI C0116 4-Chloroaniline-3-sulfonic Acid (CAS 88-43-7) is a trifunctional aromatic building block bearing amino, sulfonic acid, and chloro groups on a single benzene ring. It is widely used in diazotization and azo coupling reactions for dye and pigment intermediate synthesis. The sulfonic acid group imparts water solubility, which is valuable when designing aqueous-compatible colorants and probes. Supplied by TCI in 25 g and 500 g packs, it suits both bench-scale research and repeated synthetic work.
