Used in pharmaceutical synthesis as a key intermediate for angiotensin II receptor antagonists, particularly in the production of valsartan and related sartans. The biphenyl core with protected aminomethyl and acetic acid groups facilitates efficient coupling reactions to build the essential biaryl-tetrazole scaffold. Commonly employed in research and industrial settings for developing antihypertensive medications. The Boc protecting group allows selective deprotection in multi-step syntheses, ensuring high purity and yield.
