Used as an intermediate in the synthesis of sulfonamide-based pharmaceuticals, particularly in the development of antimicrobial and antifungal agents. Its structure supports the formation of bioactive molecules that can inhibit carbonic anhydrase enzymes, making it valuable in research for drugs targeting glaucoma and epilepsy. Also employed in the preparation of dyes and functional materials due to its aromatic amine and sulfonamide groups, which enhance binding and solubility properties.
