4’-(Bromomethyl)biphenyl-2-carboxylic acid tert-butyl ester（Cat No.:R056040）is a specialized organic intermediate featuring a biphenyl core with a bromomethyl substituent and a tert-butyl ester-protected carboxylic acid. With the molecular formula C₁₈H₁₉BrO₂, it is commonly used in pharmaceutical and material science synthesis, particularly for introducing biphenyl units into complex molecules. The bromomethyl group enables further functionalization via nucleophilic substitution, while the tert-butyl ester protects the carboxylic acid during multi-step reactions. Its structural stability and functional versatility make it valuable for constructing biologically active compounds and advanced organic frameworks in research and development.
