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 due to its nitrogen-rich structure. Additionally, finds use in materials science for developing energetic materials and corrosion inhibitors.
