Used as a key intermediate in the synthesis of neonicotinoid insecticides, particularly chloropyridine-based agrochemicals like imidacloprid. It is essential for producing crop protection products effective against a broad spectrum of insect pests, such as aphids, whiteflies, and other sap-sucking insects. The neonicotinoids synthesized from this intermediate bind strongly to insect nicotinic acetylcholine receptors, causing paralysis and death. These insecticides exhibit systemic properties, allowing absorption into plants for application via foliar spray, dusting, or root uptake, providing long-term pest control and reducing the frequency of chemical applications. Additionally, it is utilized in research to develop new pesticides with improved selectivity and lower environmental impact.
