Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based pharmaceuticals. It serves as a reagent in the development of bioactive molecules, including antimicrobial and anti-inflammatory agents. Its hydroxylamine functionality allows it to act as a nucleophile in coupling reactions, making it valuable in the synthesis of heterocyclic compounds. Also employed in research settings for modifying sulfonamide structures to enhance drug solubility and metabolic stability.
