Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as valsartan and other sartan-class antihypertensive drugs. Its tetrazole ring serves as a bioisostere for the carboxylic acid group, enhancing metabolic stability and improving pharmacokinetic properties in pharmaceuticals. 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 energetic materials due to the high nitrogen content and thermal stability of the tetrazole moiety.
