  • Applications

    1-(2-Furanyl)-2-butanone (CAS 4208-63-3) is primarily used as an intermediate in organic synthesis and as a fragrance-building block. In the fragrance and personal care fields, it may serve as a fragrance intermediate or precursor contributing to woody and caramel notes, helping to define characteristic aroma profiles. It may be evaluated for use in household products as a fragrance component for cleaners, air fresheners, and similar formulations. In industrial manufacturing, it can serve as a starting material for the preparation of functionalized furyl ketone derivatives used in specialty chemicals and may act as a precursor to compounds for polymers or coatings. Its use is typically subject to formulation limits and local regulatory requirements.
