  • Applications

    Chemical name: 2,3,4,5-Tetramethylphenol; CAS number: 488-70-0 is used as a chemical building block in organic synthesis of specialty chemicals, including fragrances, dyes, and pharmaceutical intermediates; it also serves as a hindered phenolic antioxidant and stabilizer in polymer formulations, coatings, and lubricants; in perfumery and flavor contexts it can function as an odorant component or fragrance precursor; in coatings and inks formulations it can act as a reactive aromatic scaffold for formulation components and as a starting point for developing UV/light-stabilizing additives in electronic-related materials; these applications are typically realized under controlled formulation conditions and in compliance with local regulations.
