  • Applications

    2-(Heptadecyl)furan (CAS 208329-97-9) is often considered a fragrance ingredient and perfumery fixative, with its long aliphatic tail contributing to enduring aroma notes; it may also be used in cosmetics and personal care as a scent component. In household products, it can serve as an aroma additive in cleaners and related formulations. In industrial manufacturing, it may function as an intermediate in organic synthesis or as a processing aid or specialty solvent in niche formulations. In polymers and coatings, it could act as a modifier or compatibilizer to influence surface properties and hydrophobicity. Use is subject to local regulations and formulation limits.
