Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks. The aldehyde and boronic acid functional groups allow sequential transformations, enabling the synthesis of complex molecules such as drug candidates and functional materials. Its protected phenol group (benzyloxy) can be deprotected under mild conditions, offering selective reactivity in multi-step syntheses. Commonly employed in the development of kinase inhibitors and other bioactive compounds.
