Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as losartan and valsartan. Its structure enables effective coupling in medicinal chemistry pathways, making it valuable for developing pharmaceuticals that regulate blood pressure. Also employed in research for designing novel bioactive molecules due to the tetrazole ring’s ability to mimic carboxylic acid groups, enhancing metabolic stability and bioavailability in drug candidates.
