Widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing biaryl frameworks found in pharmaceuticals, agrochemicals, and advanced materials. The boronate ester group enables efficient coupling with aryl halides under palladium catalysis, while the aldehyde functionality allows for further derivatization, such as condensation reactions or reduction to alcohols. Its dual functional groups make it valuable in the development of complex organic molecules, including liquid crystals, organic semiconductors, and drug intermediates. It is also employed in the synthesis of conjugated polymers and metal-organic frameworks due to its structural rigidity and reactivity.
