  • Applications

    2,3,6-Trimethylphenol (CAS 2416-94-6) is an aromatic phenolic compound bearing three methyl groups that serves mainly as a key intermediate for the industrial synthesis of α-tocopherol (vitamin E), a precursor for antioxidant additives for plastics and rubber, a building block for UV stabilisers, selective agrochemicals, pharmaceutical intermediates, fragrance ingredients, alkyd resins, dyes and specialty pigments; it is also employed in laboratories as an analytical standard, in mechanistic studies of phenolic redox chemistry, and in the preparation of functional oligomers and polymers, thereby making it valuable across the pharmaceutical, nutraceutical, petrochemical, engineering plastics and specialty chemical sectors.
