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 constructing complex organic molecules, especially in drug discovery and development of functional materials. The presence of bromo and ethoxy substituents allows for selective and sequential functionalization, enhancing its utility in multi-step synthetic routes.
