Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its boronate ester group facilitates efficient coupling with aryl or vinyl halides under palladium catalysis, making it valuable in pharmaceutical, agrochemical, and materials science research. Particularly useful in constructing biaryl or conjugated systems found in functional organic materials and bioactive compounds. The bromo group allows for further selective derivatization, enhancing its versatility in multi-step syntheses.
