QUICK LINKS

Sodium tartrate dibasic is a chelating agent that functions by forming coordination complexes with metal ions. In aqueous solutions, it can sequester metal ions such as calcium, magnesium, and copper, preventing them from participating in various chemical reactions. By binding to metal ions, it may influence the behavior of certain enzymatic reactions and biochemical pathways that are sensitive to metal ion concentrations. This chelating property may be useful in experimental applications where the precise control of metal ion concentrations is necessary for studying the effects of metal ions on biological systems or chemical reactions. Sodium tartrate dibasic can also be utilized to stabilize certain solutions or suspensions by preventing the precipitation of metal salts.
