  • Applications

    Delfone (CAS 4819-67-4) is typically used as an intermediate in organic synthesis; as a solvent or co-solvent and processing aid in industrial manufacturing, particularly in coatings, inks, and adhesives; as a fragrance ingredient or odorant and potentially as a fixative in perfumery; as a solvent or carrier in cosmetics and personal care formulations; as a solvent component in cleaning products; and is sometimes evaluated for use as a processing aid in polymer or plastics processing.
