Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of fluorinated quinoline derivatives, which are important in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in the development of bioactive molecules and functional materials. Commonly applied in medicinal chemistry for constructing libraries of nitrogen-containing heterocycles with potential antitumor, antimicrobial, or kinase inhibitory activities.
