Used as a key intermediate in the synthesis of neonicotinoid insecticides, particularly in the production of clothianidin. It plays a critical role in agrochemical manufacturing due to its ability to form chloropyridinylmethyl derivatives that target insect nervous systems. Its structure allows for efficient coupling reactions in pesticide development, making it valuable in creating crop protection agents effective against sucking and chewing pests. Commonly utilized in fine chemical synthesis where halogenated pyridine moieties are required.
