Used in the synthesis of sartan-class antihypertensive drugs, particularly as an intermediate in the preparation of angiotensin II receptor antagonists. Its tetrazole ring mimics the carboxylate group in angiotensin II, enabling effective binding to the AT1 receptor. The chloro and sulfonamide groups allow further functionalization, making it valuable in medicinal chemistry for developing potent blood pressure-lowering agents. Also employed in research for designing new heterocyclic compounds with potential cardiovascular activity.
