Used primarily in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. Its boronate ester group facilitates coupling with aryl or heteroaryl halides, making it valuable in the development of pharmaceuticals, agrochemicals, and advanced materials such as organic light-emitting diodes (OLEDs). The quinoline core provides structural stability and electronic properties useful in designing functional molecules. Its application is especially prominent in medicinal chemistry for constructing complex aromatic systems.
