Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a sulfonamide-based building block in the development of bioactive molecules due to its ability to participate in nucleophilic substitution reactions. Commonly employed in the synthesis of nitrogen-containing heterocycles and as a protecting group reagent in peptide chemistry. Its nitro group allows for further functionalization through reduction to an amine, enabling the construction of more complex molecular architectures. Also utilized in research settings for the development of new synthetic methodologies and in the production of dyes and functional materials.
