Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active quinoline derivatives. It enables the formation of carbon-carbon bonds, particularly in pharmaceutical and agrochemical research, where quinoline scaffolds are prevalent. Its boronic acid group facilitates mild and selective coupling with aryl or heteroaryl halides, making it valuable in drug discovery for building complex molecules. Also employed in the development of fluorescent probes and organic electronic materials due to the quinoline core’s photophysical properties.
