Used as a key intermediate in the synthesis of neonicotinoid insecticides, particularly in the production of clothianidin and related agrochemicals. Its structure allows for efficient transformation into biologically active compounds that target insect nervous systems. Widely utilized in crop protection for systemic pest control, especially in seed treatments for corn, soybeans, and cereals. Also serves in research for developing new chlorinated nicotinyl derivatives with improved selectivity and environmental profiles.
