  • Applications

    Dipropyl oxalate (CAS 615-98-5) is primarily used as a plasticizer for polymers such as PVC and certain cellulose-based resins, improving flexibility and processability. It is also employed as a solvent or co-solvent in coatings, inks, and adhesive formulations to tune volatility and solvency. As an organic synthesis intermediate, Dipropyl oxalate is commonly used as a precursor to more complex oxalate esters or other chemical intermediates. In perfumery, it can be evaluated as a fragrance fixative or aroma component, contributing to longer-lasting notes. Additionally, it may serve as a processing solvent or additive in plastic and coating formulation workflows.
