Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. Its boronic acid group enables efficient coupling with aryl halides, making it valuable in the development of quinoline-based bioactive molecules. Commonly applied in medicinal chemistry for constructing kinase inhibitors and antimicrobial agents. Also utilized in materials science for creating fluorescent probes and organic electronic materials due to the quinoline core’s photophysical properties.
