  • Applications

    1,2-Bis(3,5-di-tert-butyl-4-hydroxyhydrocinnamoyl)hydrazine (CAS 32687-78-8) is primarily used as a high-performance hindered phenolic antioxidant/stabilizer for polymer formulations, plastics, and related materials, helping to retard thermal and oxidative degradation. It is also commonly evaluated for use in coatings and inks to improve film and color stability, in adhesives and sealants to enhance aging resistance, and as an antioxidant additive in lubricants and metalworking fluids and other industrial formulations.
