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 heterocyclic systems. Commonly employed in cross-coupling reactions due to the presence of the iodine moiety, enabling the formation of carbon-carbon bonds in drug discovery processes. Also utilized in the preparation of agrochemicals and functional materials where fluorinated and halogenated pyridine derivatives are required.
