Used as an intermediate in the synthesis of sulfonamide-based pharmaceuticals, particularly in the development of antimicrobial and antidiabetic agents. It serves as a building block in medicinal chemistry for modifying pharmacokinetic properties of drug candidates. Also employed in the preparation of dyes and pigments due to its aromatic sulfonamide structure, enhancing solubility and stability. Its derivatives are explored in research for enzyme inhibition, especially in carbonic anhydrase inhibitors for treating glaucoma.
