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 structure enables effective binding to the angiotensin II receptor, helping regulate blood pressure. The compound’s tetrazole ring serves as a bioisostere for the carboxylic acid group, improving metabolic stability and oral bioavailability in pharmaceutical formulations. It is widely utilized in medicinal chemistry for developing cardiovascular therapeutics.
