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 tetrazole ring mimics the carboxylic acid group in biological systems, enhancing binding affinity to the angiotensin II receptor. Also employed in coordination chemistry as a ligand due to its ability to form stable complexes with metal ions. Additionally, it finds use in the development of agrochemicals and in materials science for designing nitrogen-rich compounds.
