Used as a key 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 receptors. Also employed in coordination chemistry as a ligand for metal ions, forming complexes with potential catalytic or material science applications. Additionally, it finds use in the development of sensors and functional materials due to its ability to participate in hydrogen bonding and metal coordination.
