Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) for drugs targeting central nervous system disorders and anti-inflammatory agents. It serves as a building block in organic reactions, especially in the development of nitro-substituted aromatic compounds. Its aldehyde and nitro functional groups allow for versatile transformations, including reduction, condensation, and cyclization reactions. Commonly employed in the preparation of dyes, agrochemicals, and specialty chemicals where chloro-nitro aromatic scaffolds are required. Also utilized in research laboratories for the development of novel heterocyclic compounds with potential biological activity.
