Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as candesartan and valsartan. Its tetrazole ring mimics the carboxylic acid group in angiotensin II, allowing it to effectively bind to the AT1 receptor. This compound contributes to the enhanced bioavailability and receptor affinity of the final drug product. It is also employed in medicinal chemistry research for developing new bioactive molecules due to the tetrazole moiety’s metabolic stability and ability to participate in hydrogen bonding.
