  • Applications

    Ethyl 2-ethylbutyrate (CAS 2983-38-2) is a branched fatty ester widely used as an odorant and flavoring agent in industrial formulations. In perfumery, it contributes a fruity, pineapple-like note as a fragrance ingredient; in the flavor sector, it is evaluated for use as a fruit-flavor/aroma compound in confections and beverages. In cosmetics and personal care, it appears as a fragrance component in products such as creams, lotions, and shampoo formulations. In household products, it is employed as a fragrance additive in cleaners and air fresheners. In coatings and inks, it can function as a solvent or co-solvent in formulation systems; and in chemical manufacturing, it serves as an intermediate for synthesizing more complex fragrances or aroma chemicals.
