  • Applications

    Ethoxymethylfurfural (CAS 1917-65-3) is a biomass-derived platform chemical commonly evaluated as an intermediate for the production of bio-based monomers and polymers, including polyesters and resins. It serves as a reactive building block for derivatives used in coatings, inks, and adhesives, and can function as a solvent or processing aid in organic synthesis and formulation work. In fragrance and flavor contexts, EMF and its derivatives are explored as aroma intermediates or fixatives. It can also be converted to other value-added furanic chemicals by oxidation or functionalization, enabling downstream generation of acids, esters, and specialty monomers. Use is subject to local regulations and formulation limits.
