  • Applications

    Disodium alpha-sulfoglycolate (CAS 29736-24-1) is used as a chelating agent to sequester metal ions in cleaning formulations and industrial processes, helping prevent scale and metal-catalyzed degradation; it can also function as a processing aid and stabilizer in polymer and plastic formulations; it may serve as a dispersant in coatings and inks to improve pigment stability and dispersion; it is often employed as an intermediate in organic synthesis, providing a versatile building block for sulfated glycolate derivatives; in electronics-related manufacturing, it can act as a complexing agent in metal finishing and electroplating baths.
