Used as an intermediate in the synthesis of agrochemicals, particularly insecticides that act on the insect nervous system. It is effective against various crop pest insects by mimicking the neurotransmitter acetylcholine, leading to disruption of the nervous system and death. This compound is commonly used in the development of highly specific insecticides with low environmental residue. Its chlorinated pyridine core enhances stability and bioactivity, allowing further functionalization for novel crop protection agents. Also utilized in laboratory settings for the preparation of pyridine-based derivatives in medicinal chemistry.
