Used primarily as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its boron-containing group facilitates coupling with aryl or vinyl halides under palladium catalysis, making it valuable in the preparation of complex aromatic compounds, pharmaceuticals, and functional materials. The presence of bromine atoms allows for selective, sequential coupling reactions, offering versatility in multi-step syntheses. Commonly employed in research and development of organic electronic materials and bioactive molecules.
