Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to create complex biaryl compounds. These compounds are essential in pharmaceuticals, agrochemicals, and materials science. Its boronic acid group enables efficient coupling with aryl halides, while the formyl group allows further functionalization. Commonly applied in the development of drug candidates, sensors, and advanced polymers. Its versatility makes it valuable in research and industrial applications.
