  • Applications

    Monosodium aspartate (CAS 3792-50-5) may be used as a chelating agent in cleaning formulations and industrial detergents to bind metal ions and support stability; as a nutrient source in cell culture media and fermentation feeds to supply aspartate; as an intermediate or building block in the synthesis of amino acid derivatives; as a buffering or formulation stabilizer in cosmetics and personal care products; and as a component in agricultural nutrient solutions to provide nitrogen and aid micronutrient delivery.
