Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its aldehyde and boronate functional groups allow dual reactivity, enabling sequential transformations to build aromatic frameworks. Commonly employed in the development of bioactive compounds and functional materials where precise molecular architecture is required. The boronate ester group facilitates palladium-catalyzed coupling with aryl halides, while the aldehyde can be further modified through reduction, condensation, or nucleophilic addition reactions.
