Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan and valsartan, which are widely prescribed for hypertension. Its tetrazole ring mimics the carboxylic acid group in biological systems, enhancing metabolic stability and bioavailability. Also employed in coordination chemistry as a ligand for metal ions due to the nitrogen-rich structure. Finds use in medicinal chemistry for building heterocyclic compounds with potential antimicrobial or anti-inflammatory activity.
