Used as an intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan and candesartan, which are widely prescribed for hypertension and cardiovascular diseases. Its tetrazole ring mimics the carboxylic acid group in biological systems, enhancing binding affinity to the AT1 receptor. Also employed in coordination chemistry as a ligand for metal complexes due to the nitrogen-rich tetrazole moiety. Shows potential in materials science for developing energetic materials and corrosion inhibitors.
