Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a building block in the preparation of compounds with potential neuroactive properties, including agents studied for cognitive disorders and neurological diseases. Its chloropyridine core allows for further functionalization, enabling the creation of diverse derivatives for structure-activity relationship studies in medicinal chemistry. Also employed in agrochemical research for the design of novel pesticides targeting insect nervous systems.
