Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogen substituents allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki, Stille, and Negishi couplings to introduce the pyridine scaffold into target molecules. Also utilized in the preparation of functional materials and ligands for catalysis.
