Used in the synthesis of angiotensin II receptor antagonists, particularly in the development of sartan-class antihypertensive drugs. The tetrazole ring mimics the carboxylic acid group in biological activity, enhancing binding to the AT1 receptor. This compound serves as a key intermediate in pharmaceuticals like losartan and candesartan, contributing to improved metabolic stability and oral bioavailability. Also employed in medicinal chemistry research for designing new bioactive molecules due to the tetrazole moiety’s ability to act as a pharmacophore.
