This compound is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a key intermediate for constructing complex aromatic systems. Its boronate ester group allows for efficient coupling with aryl halides, enabling the formation of biaryl structures, which are essential in pharmaceuticals, agrochemicals, and materials science. Additionally, the aldehyde functional group provides a versatile handle for further chemical modifications, such as condensation or reduction reactions, making it valuable in the synthesis of fine chemicals and polymers. Its stability and reactivity under mild conditions make it a preferred choice in modern synthetic chemistry.
