2,3-Dichloropyridine（Cat No.:R070426）is a halogenated heteroaromatic compound with the molecular formula C5H3Cl2N. It features a pyridine ring substituted with chlorine atoms at the 2 and 3 positions, making it a useful intermediate in organic synthesis. This colorless to pale yellow liquid exhibits reactivity suitable for nucleophilic aromatic substitution, especially in the development of pharmaceuticals, agrochemicals, and advanced materials. The electron-withdrawing effect of the chloro groups alters the ring’s electronic properties, enabling selective transformations. 2,3-Dichloropyridine is often employed in the preparation of heterocyclic compounds and complex functional molecules.
