  • Applications

    Methionylmethionine (CAS 52715-93-2) is primarily used as a methionine source in animal nutrition, supplying methionine in a dipeptide form that is readily absorbed by livestock and poultry. It is also employed as an intermediate in peptide synthesis and in derivatives of amino acids for pharmaceutical research and development. In cosmetics and personal care, it may function as a skin- and hair-conditioning dipeptide. As a dipeptide chemical, it can serve as an intermediate for the synthesis of short peptide sequences or peptide-based polymer materials.
