Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the development of sartan-class antihypertensive drugs. Its tetrazole ring mimics the carboxylic acid group in biological systems, enhancing binding affinity to the AT1 receptor. Commonly employed in pharmaceutical research for optimizing drug candidates targeting cardiovascular diseases. Also utilized in the preparation of functionalized heterocyclic compounds for medicinal chemistry and drug discovery programs.
