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 for selective cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic molecules. Commonly employed in medicinal chemistry for modifying pyridine-based scaffolds to enhance binding affinity or metabolic stability. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and structural properties.
