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 supports the formation of biologically active heterocyclic compounds that modulate blood pressure. Also employed in click chemistry and cycloaddition reactions due to the tetrazole ring’s ability to mimic carboxylic acid groups, enhancing metabolic stability in pharmaceuticals. Shows potential in coordination chemistry as a ligand for metal ions in catalytic systems.
