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 structure enables efficient coupling reactions in pharmaceutical manufacturing, contributing to the development of medications that regulate blood pressure by blocking vascular constriction. Also employed in research for developing new bioactive molecules due to the tetrazole ring’s ability to mimic carboxylic acid groups, enhancing metabolic stability and solubility in drug candidates.
