Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as losartan and valsartan. 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. Shows potential in the development of new pharmaceuticals due to its ability to participate in hydrogen bonding and dipole interactions with biological targets.
