  • Applications

    Methyl 2-ethyloctanoate (Octanoic acid, 2-ethyl, methyl ester) is used primarily as a fragrance ingredient in perfumery and cosmetics, imparting fruity notes; it also serves as a solvent and processing aid in industrial manufacturing, including coatings, inks, and cleaning formulations. It may be considered as a flavor/aroma ingredient in selected food and beverage applications under regulatory approvals, and can function as an intermediate in organic synthesis as well as a plasticizer or processing aid in certain polymers, depending on formulation and regulatory constraints.
