Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the preparation of losartan and related sartan-class antihypertensive drugs. The bromomethyl group allows for nucleophilic substitution reactions, enabling the introduction of heterocyclic moieties, while the Boc-protected biphenyl scaffold provides stability and selectivity during multi-step syntheses. Commonly employed in pharmaceutical research and development for constructing complex biaryl structures with high functional group tolerance.
