Widely used as a key intermediate in the synthesis of neonicotinoid insecticides and related agrochemicals. Its structure allows for efficient functionalization, making it valuable in creating active ingredients that target insect nervous systems. It is also employed in the development of other crop protection agents due to its reactivity and stability in multi-step chemical processes. Additionally, it finds use in research for novel pesticides and pharmaceuticals where chlorinated heterocyclic scaffolds are required.
