Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs like losartan and valsartan. Its hydrazide and tetrazole functional groups enable efficient coupling reactions in heterocyclic compound development. Also employed in medicinal chemistry for designing bioactive molecules due to the metabolic stability and hydrogen bonding capability of the tetrazole ring. Shows potential in coordination chemistry as a ligand for metal ions in catalytic systems.
