Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based pharmaceuticals. It serves as a protecting group for amines due to its ability to block reactive amine sites during multi-step syntheses. The nitro group allows for further functionalization through reduction to an amino group, enabling the construction of complex molecules. Commonly employed in the development of agrochemicals, dyes, and bioactive compounds where controlled reactivity and selective transformations are required. Its stability under various reaction conditions makes it valuable in peptide synthesis and medicinal chemistry.
