  • Applications

    Dihydrogen bis(L-glutamato(2-)-N,O1)zincate(2-) is a zinc–amino acid chelate that can function as a metal chelating agent in cleaning formulations and cosmetics, helping to sequester trace metals and improve formulation stability. It may serve as a bioavailable zinc source in animal nutrition and could be considered for specialty dietary supplements, subject to regulatory limits. In polymer and plastics processing, the complex can act as a stabilizer or processing aid via metal coordination, potentially influencing color stability and shelf life. It may also be used as an intermediate or precursor in the synthesis of other zinc–amino acid chelates for research and industrial applications, subject to formulation controls and regulations.
