Used as an intermediate in the synthesis of sulfonamide-based pharmaceuticals, particularly in the development of antimicrobial and anti-inflammatory agents. It serves as a key building block in organic synthesis due to the presence of both nitro and sulfonamide functional groups, which can be selectively modified. Commonly employed in the preparation of dyes and pigments, especially in azo dye formulations where the nitro group enhances electron-withdrawing properties. Also utilized in research settings for the development of new bioactive compounds and in the production of agrochemicals as a precursor for herbicides and plant growth regulators.
