  • Applications

    Dipropyl maleate (CAS 2432-63-5) is a diester of maleic acid with propanol. In industrial applications it is primarily used as a plasticizer for PVC and other polymers to improve flexibility and processability. It also serves as a solvent or viscosity modifier and as a reactive diluent or monomer that can participate in crosslinking in coatings, resins, and polyester or alkyd systems, enabling tailored film properties. As an organic synthesis intermediate, dipropyl maleate is used to prepare other maleate derivatives and to participate in polymerization reactions. In formulation work, it may act as a processing aid or reactive additive, subject to local regulations and formulation limits.
