Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like losartan and related sartan-class medications. Its tetrazole ring mimics the carboxylic acid group in biological systems, enhancing binding to the angiotensin II receptor. This compound plays a critical role in improving the potency and metabolic stability of these drugs. It is widely utilized in pharmaceutical research and development for cardiovascular therapies.
