EXTERNAL LINKS & GENERAL DESCRIPTION
Wikipedia Linking (Sultone) Material Safety Data Sheet Google Scholar Search Local: Sultone is an internal cyclic monoester (anhydride) derived from the hydroxyl and sulfonic radicals, with the formula -OSO₂-.in a ring system. It is an analogous to lactone. Sultam (a cyclic amide) is the nitrogen analog of sultone. Cyclic sulfur structure and analogues are important nucleuses in pharmacological activity and in printing textile materials. Sultone is used as a chemical intermediate to introduce cyclic sulfo groups into target molecules and to provide water affinity and anionic character. Propane sultone is a source sulfopropyl group into target organic molecules which are used as surfactants, lather treatment chemicals, biocides and corrosion inhibitor.
