Used as a key 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 constructing complex pyridine-based molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to form carbon-carbon or carbon-nitrogen bonds. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogen substitution pattern that enhances reactivity and binding affinity.
