Used in Suzuki-Miyaura cross-coupling reactions to synthesize complex quinoline derivatives, which are important in pharmaceutical and agrochemical industries. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions. Commonly applied in the development of bioactive molecules, organic semiconductors, and fluorescent probes due to the quinoline moiety’s electron-accepting properties. Also utilized in materials science for constructing conjugated systems in OLEDs and sensors.
