Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronic acid group enables efficient carbon-carbon bond formation with aryl halides, making it valuable in constructing biaryl structures found in bioactive compounds. The presence of chloro, fluoro, and ester functional groups allows further selective modifications, enhancing its utility in drug discovery and development of functional materials.
