Used as a key intermediate in the synthesis of neonicotinoid insecticides, particularly in the production of imidacloprid and related compounds. It plays a critical role in agricultural pest control by contributing to the development of systemic insecticides that target sucking insects such as aphids, whiteflies, and leafhoppers. Its structure allows for effective binding to insect nicotinic acetylcholine receptors, leading to paralysis and death of the pest. Due to its reactivity and selectivity, it is preferred in multi-step organic synthesis for introducing chloropyridinyl moieties in agrochemicals.
