Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It serves as a building block in the preparation of sulfonamide-based compounds, which are important in the design of bioactive molecules. Its nitro group allows for further functionalization through reduction to an amine, enabling the formation of more complex structures. Commonly employed in research settings for the synthesis of dyes, fluorescent probes, and potential drug candidates targeting enzymes or receptors where sulfonamides exhibit inhibitory activity.
