Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It plays a key role in the production of certain neonicotinoid insecticides, which are effective against a broad spectrum of insect pests. Its chlorinated structure enhances reactivity, making it valuable in building complex heterocyclic compounds. Also explored in research for developing new bioactive molecules due to its ability to participate in substitution reactions. Limited use in industrial applications due to sensitivity and handling requirements.
