Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the production of quinoline-based drugs, including antimalarial and anticancer agents. Employed in cross-coupling reactions, such as Suzuki and Heck reactions, to form carbon-carbon bonds in fine chemical manufacturing. Also utilized in the development of ligands for metal catalysts and in materials science for creating fluorescent dyes and optoelectronic materials.
