Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boron-containing structure allows efficient coupling with aryl halides under palladium catalysis, making it valuable in the preparation of complex organic molecules, especially in drug discovery and materials science. Stable and easy to handle, it serves as a versatile building block for introducing chlorophenyl groups into target compounds.
