Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as valsartan and losartan. Its tetrazole ring serves as a bioisostere for the carboxylic acid group, enhancing metabolic stability and improving pharmacokinetic properties. Also employed in coordination chemistry as a ligand for metal ions in catalytic systems. Additionally, it finds use in the development of energetic materials due to the high nitrogen content contributing to thermal stability and energy density.
