  • Applications

    Sodium bitartrate (CAS 526-94-3) is a water-soluble salt commonly used as an acidity regulator and buffering agent in food processing; as a stabilizer and chelating agent in cleaning and detergent formulations; as a pharmaceutical excipient and pH-control additive in formulation development; as a buffering agent and tartrate source in cosmetics/personal care and in certain polymer and coating systems; and as a reagent or intermediate in organic synthesis, including enantioselective routes.
