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 mimics the carboxylic acid group in biological systems, enhancing binding to the AT1 receptor. Also employed in coordination chemistry to form metal-organic frameworks due to its ability to act as a multidentate ligand. Additionally, it serves as a building block in click chemistry and pharmaceutical research for developing bioactive molecules.
