Used in Suzuki-Miyaura cross-coupling reactions to synthesize complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronic acid group enables carbon-carbon bond formation with aryl or vinyl halides, facilitating the construction of biaryl structures. The presence of bromine allows for sequential coupling reactions, offering versatility in multi-step synthesis. Commonly applied in the development of bioactive compounds and functional materials where precise molecular architecture is required.
