  • Applications

    2,6,10-Trimethyldodeca-2,6,10-triene (CAS 7681-88-1) is a sesquiterpene hydrocarbon. In real-world applications, it is considered as a fragrance ingredient in perfumery and cosmetics, and may be used as a fragrance additive in household products such as cleaners. It can also serve as an intermediate or starting material for the synthesis of other aroma compounds and as a component in polymer or coating formulations where natural aroma notes are desired. Additionally, it may function as an odorant in coatings and inks, subject to formulation constraints and regulatory considerations.
