Used as a key intermediate in the synthesis of neonicotinoid insecticides, particularly in the production of clothianidin and related compounds. It plays a critical role in agrochemical manufacturing due to its ability to introduce specific functional groups into the pyridine ring system, enhancing the biological activity of the final pesticide products. Its reactivity makes it valuable for forming carbon-nitrogen and carbon-sulfur bonds during multi-step syntheses. Commonly handled in controlled environments due to its sensitivity and reactivity.
