  • Applications

    Monosodium succinate (CAS 2922-54-5) is used as a pH buffering and stabilizing agent in fermentation and bioprocessing, helping maintain stable buffer systems during enzyme production and other biotechnological operations. It is also employed as a starting material or intermediate in the synthesis of succinyl-containing compounds for chemicals and pharmaceuticals. Additionally, the monosodium salt can function as a metal-ion chelating agent in cleaning formulations and cosmetic preparations, aiding sequestration of metal ions and formulation stability. In plastics and polymers processing, it may serve as a precursor or processing aid influencing resin properties. The salt may be evaluated for use as an acidity regulator or formulation buffer in select regulated products where permitted by local regulations.
