Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Commonly applied in pharmaceutical development and agrochemical research for constructing biaryl structures. Its boronate ester group facilitates palladium-catalyzed coupling with aryl halides under mild conditions, making it valuable in medicinal chemistry for building drug-like scaffolds. Also employed in materials science for designing organic semiconductors and functional polymers.
