  • Applications

    Diisopropyl succinate (CAS 924-88-9), a diester of succinic acid with isopropanol, is primarily used as a plasticizer for polymers and resins (e.g., PVC and polyesters) to improve flexibility and processability; as a solvent or co-solvent in coatings, inks, and cleaning formulations; as a chemical intermediate in the synthesis of other esters and specialty compounds; and considered a useful processing additive in plastics and coatings to improve handling and physical properties.
