  • Applications

    2,5-Dimethyl-2-undecene can serve as a fragrance ingredient or odorant in perfumery and cosmetics, contributing to scent profiles in personal care products. It may be evaluated as a fragrance component for household products where a non-polar hydrocarbon helps impart and complement aromas. In polymers and plastics, it may function as a specialty additive or processing aid to influence manufacturing behavior and material properties. As an organic intermediate, it can participate in organic synthesis to generate other specialty chemicals used in industrial production. In coatings and inks, it can act as a processing aid or solvent-like component to adjust flow, evaporation, and film formation, subject to local regulations and formulation limits; chemical name: 2,5-Dimethyl-2-undecene; CAS: 49622-16-4.
