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, making it valuable in medicinal chemistry for creating targeted drug candidates. Also employed in agrochemical research for designing novel pesticides and herbicides due to its halogenated pyridine core, which can enhance binding affinity and metabolic stability. Commonly utilized in cross-coupling reactions, such as Suzuki or Heck reactions, to build complex aromatic systems in both drug discovery and materials science.
