Used as a key intermediate in the synthesis of agrochemicals, particularly neonicotinoid insecticides that act as agonists on nicotinic acetylcholine receptors (nAChR) in insects for effective pest control. Its halogenated pyridine structure enables selective reactivity in coupling reactions, making it valuable in building complex molecules for crop protection agents with high specificity and low environmental toxicity. Also employed in research for designing novel bioactive compounds and pharmaceuticals.
