Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the development of sulfonamide derivatives and other sulfur-containing compounds. Its nitro group allows for further functionalization through reduction to an amine, enabling coupling reactions in the synthesis of dyes and functional materials. Also employed in research for studying nucleophilic aromatic substitution reactions due to the electron-withdrawing nature of the nitro group enhancing reactivity at the aromatic ring.
