We provides three series of sulfonation products—1,3-Propanesultone, 1,4-Butanesultone, Sodium 3-Chloro-2-Hydroxypropanesulfonate—along with their full range of sulfonic acid derivatives. These serve as excellent functional products for electronic electroplating, biological buffers, polymer modification, and the synthesis of anionic/zwitterionic functional materials.
