  • Applications

    2,4-Dimethyl-6-(1-methylpentadecyl)phenol (CAS 134701-20-5) is a lipophilic hindered phenol that is commonly evaluated for use as a fragrance ingredient and odorant with potential as a fixative in perfumery and cosmetic formulations. It also serves as a stabilizer/antioxidant in industrial polymers, plastics, rubber, and lubricants, helping to prevent oxidative degradation during processing and service life. In coatings and inks, it may function as a processing additive or stabilizer to improve durability and color stability. It can be employed as an aromatic intermediate in chemical synthesis, enabling further functionalization to access related compounds. Additionally, it may be encountered as a component in household products (fragrance formulations) where it contributes scent profile and odor retention, subject to formulation limits and regulatory requirements.
