  • Applications

    (-)-Catechin gallate, CAS 130405-40-2, is a polyphenolic compound primarily explored for its antioxidant properties. In industrial contexts, it is used as an antioxidant additive in cosmetics and personal care formulations; as an oxidative stabilizer for polymers, plastics, and coatings; and as a building block or intermediate in organic synthesis of polyphenol-based compounds. It is also evaluated for use in coatings and printing inks as a stabilizing antioxidant additive. In pharmaceutical and biomedical research, catechin gallate is studied as a polyphenol scaffold for developing new derivatives and exploring structure–activity relationships, within the bounds of typical experimental research and formulation development.
