  • Applications

    Diethyl azelate (CAS 624-17-9), the diester of azelaic acid (nonanedioic acid), is primarily used as a non-phthalate plasticizer and processing aid for polymers such as PVC and polyesters, improving flexibility and film formation. It also serves as a solvent and plasticizer in coatings, inks, and adhesive formulations, aiding dispersion and performance. As a chemical intermediate, it is used in the synthesis of specialty plasticizers and lubricant additives for polymer systems. In cosmetics and personal care, it may function as a lightweight emollient or solvent in formulations. It may also be considered as a solvent component in cleaning formulations, depending on local regulations and formulation limits.
