Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the preparation of sartan-class antihypertensive drugs. Its structure allows for the introduction of biphenyl and tetrazole moieties, which are critical for biological activity in blocking the angiotensin II receptor. The bromomethyl group enables alkylation reactions to form carbon-nitrogen or carbon-oxygen bonds, facilitating the assembly of complex drug molecules. Commonly employed in pharmaceutical research and development for optimizing potency and pharmacokinetic properties of cardiovascular medications.
