Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active quinoline derivatives. Its boronic acid group enables efficient carbon-carbon bond formation, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of kinase inhibitors, antimicrobial agents, and fluorescent probes due to the quinoline scaffold's inherent bioactivity and optical properties. Stable enough for standard handling, it supports high-yielding transformations under mild conditions.
