  • Applications

    Calcium bis(2-hydroxy-4-(methylthio)butyrate), CAS 4857-44-7, is commonly used as a metal ion chelating/sequestering agent in formulation systems for household and industrial cleaners, helping prevent mineral scale and improve performance. It also serves as a processing stabilizer and dispersant in polymers, plastics, coatings, and inks, aiding pigment suspension and melt processing. In water treatment and metal-finishing applications, it can function as a scale inhibitor and corrosion inhibitor, contributing to system reliability. Additionally, it is used as an intermediate in the synthesis of specialty chemicals and as a formulation-building component for advanced materials. Its exact applicability depends on formulation and local regulatory considerations.
