Used primarily as an intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides. It plays a key role in the production of chlorpyrifos, a widely used organophosphate insecticide. Its chlorinated structure makes it suitable for nucleophilic substitution reactions, enabling the development of more complex pesticide molecules. Also utilized in the preparation of certain pharmaceuticals and specialty chemicals where halogenated pyridine rings enhance biological activity or stability. Due to its reactivity, it is handled under controlled conditions in industrial settings.
