Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based pharmaceuticals. It serves as a building block in the development of bioactive molecules, including potential protease inhibitors and antimicrobial agents. Its nitro group allows for further functionalization through reduction to an amine, enabling conjugation in multi-step syntheses. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its stable sulfonyl linker and aromatic polarity.
