Used primarily as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its boronate ester group readily transmetallates with palladium catalysts, making it valuable for constructing biaryl and heterobiaryl compounds in pharmaceuticals, agrochemicals, and advanced materials. The bromo substituent allows for sequential functionalization, supporting multi-step syntheses where selective reactivity is required. Stable and easy to handle, it serves as a versatile building block in medicinal chemistry and drug development.
