Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as valsartan and losartan. Its tetrazole group mimics the carboxylate moiety of angiotensin II, enabling effective binding to the AT1 receptor. This compound plays a critical role in enhancing the potency and metabolic stability of these medications. It is widely utilized in pharmaceutical research and development for cardiovascular therapies.
