Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its halogen substituents allow selective cross-coupling reactions, making it valuable in building complex molecules. Commonly employed in the development of herbicides and fungicides due to the pyridine ring’s bioactivity. Also utilized in medicinal chemistry for constructing kinase inhibitors and other biologically active compounds. The presence of chlorine, fluorine, and iodine enables sequential functionalization, offering flexibility in synthetic routes.
