Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in organic synthesis for introducing sulfonamide functional groups into more complex molecules. Also utilized in the preparation of specialty polymers and functional materials where polar groups enhance solubility or binding characteristics. Its hydroxymethyl group allows for further chemical modification, enabling conjugation in drug design or linker applications in prodrugs and bioconjugates.
