  • Applications

    Furfuryl isobutyrate (CAS 6270-55-9) is commonly used as a fragrance ingredient and odorant in perfumery and cosmetics, providing fruity notes and potentially acting as a fixative. It may serve as a solvent or reactive diluent in coatings, resins, and inks, helping to adjust viscosity and cure behavior. It can function as a plasticizer or polymer modifier for certain plastics and resins, enhancing flexibility. It is often used as an intermediate in furfural-based resin and monomer synthesis for specialty applications such as adhesives. It may also be present in cleaning formulations as an odorant-bearing component.
