Used as an intermediate in the synthesis of dyes and pharmaceuticals, particularly in the development of sulfonamide-based antimicrobial agents. It serves as a building block in organic synthesis where the nitro group can be reduced to an amine for further functionalization. Its sulfonamide moiety is valuable in creating compounds with biological activity, including potential use in medicinal chemistry for designing enzyme inhibitors. Also employed in research settings for the preparation of specialty chemicals and agrochemicals.
