Used in the synthesis of carbonic anhydrase inhibitors, particularly in the development of sulfonamide-based pharmaceuticals for treating glaucoma and certain types of epilepsy. Its tetrazole ring acts as a bioisostere for carboxylic acid, enhancing metabolic stability and improving membrane permeability in drug candidates. Also employed in medicinal chemistry research to design novel heterocyclic compounds with potential diuretic and anticonvulsant activities.
