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 tetrazole ring mimics the carboxylic acid group in biological activity, enhancing binding affinity to the angiotensin II receptor. Commonly employed in pharmaceutical research and development for designing potent and selective cardiovascular medications. Also utilized in coordination chemistry as a ligand due to its ability to form stable complexes with metal ions.
