  • Applications

    2-Ethoxy-1-methyl-2-oxoethyl butyrate (CAS 71662-27-6) is typically used as an organic synthesis intermediate and processing aid. In industrial manufacturing, it can serve as a precursor to more complex esters and ketone-containing building blocks. It may function as a solvent or co-solvent in coatings, inks, and cleaning formulations, and could act as a reactive plasticizer in specialty polymer systems. Additionally, beta-keto ester derivatives of this type are occasionally evaluated as fragrance intermediates or odor-active compounds for perfumery and related flavor applications. Finally, it may be considered for use in cosmetics or personal care formulations as an aroma-related ingredient or formulation solvent, subject to local regulations and formulation limits.
