Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the preparation of sartan-class antihypertensive drugs such as valsartan and related analogs. The Boc-protected aminomethyl group allows for selective deprotection and further coupling in multi-step syntheses, while the tetrazole ring serves as a bioisostere for the carboxylic acid group, enhancing binding affinity to the angiotensin receptor. Its structure enables improved metabolic stability and oral bioavailability in final drug compounds. Commonly employed in pharmaceutical research and development for cardiovascular medications.
