Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogen substituents allow selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex pyridine-based structures. Commonly employed in Suzuki, Stille, and Negishi couplings to introduce the pyridine core into target molecules. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and structural properties.
