Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. It serves as a building block in the preparation of active pharmaceutical ingredients due to its reactive iodine moiety, which allows for further functionalization through cross-coupling reactions. Commonly employed in the manufacture of agrochemicals and specialty chemicals where a pyridine scaffold is required. Its derivatives are also explored in research for potential use in materials science and as ligands in catalytic systems.
