Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates efficient coupling with aryl or vinyl halides under palladium catalysis, making it valuable in the development of complex organic molecules, particularly in drug discovery and materials science. The presence of bromine allows for selective, sequential coupling reactions, enhancing its utility in multi-step syntheses. Commonly employed in research laboratories for constructing biaryl scaffolds found in bioactive compounds.
