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 mimics the carboxylic acid group in biological systems, enhancing binding affinity to the angiotensin II receptor. Also employed in coordination chemistry as a ligand for metal ions due to its nitrogen-rich structure. Additionally, finds use in the development of energetic materials and corrosion inhibitors because of its thermal stability and electron-rich framework.
