Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of pyridine-based drugs. Its reactive chloromethyl group allows for easy attachment to other molecules, making it valuable in constructing complex organic compounds. Commonly employed in the preparation of kinase inhibitors and other bioactive agents. Also utilized in agrochemical synthesis for creating novel pesticide candidates. The nitro group enhances reactivity and can be reduced to an amine for further functionalization in multi-step reactions.
