Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan and candesartan, which are widely prescribed for hypertension. Its tetrazole ring serves as a bioisostere for the carboxylic acid group, improving metabolic stability and enhancing binding affinity to the receptor. Also employed in coordination chemistry as a ligand for metal ions, forming complexes with potential catalytic or material applications. Additionally, finds use in the development of energetic materials due to its high nitrogen content and thermal stability.
