Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization in cross-coupling reactions, making it valuable in medicinal chemistry for building complex pyridine-based molecules. Commonly employed in palladium-catalyzed reactions such as Suzuki and Heck couplings to form carbon-carbon bonds. Also utilized in the preparation of agrochemicals and functional materials where halogenated heterocycles are required.
