Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of pyridine-based active ingredients. Its structure, featuring iodo and nitro groups at positions 3 and 2, allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions to introduce the pyridine moiety in drug candidates. Also utilized in research settings for the preparation of nitropyridine derivatives with potential biological activity, including reductions of the nitro group to amines for further synthetic steps.
