Used as a key intermediate in the synthesis of sulfa drugs, particularly in the production of carbonic anhydrase inhibitors. It plays a role in developing pharmaceuticals for treating glaucoma, epilepsy, and altitude sickness due to its ability to modulate enzyme activity. Its structure allows for strong binding to zinc-containing enzymes, enhancing therapeutic efficacy. Also explored in the development of diuretic agents and anti-tumor compounds owing to its sulfonamide functional group and aromatic stability.
