Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based compounds with biological activity. It serves as a protecting group for amines in multi-step synthesis due to the stability of the tert-butyl group under various reaction conditions. The electron-withdrawing nitro group enhances the electrophilicity of the sulfonamide, making it useful in nucleophilic substitution reactions. Also employed in the development of pharmaceuticals and agrochemicals where sulfonamide moieties are required for target binding or activity modulation.
