Dioctylmalonate is widely used as a plasticizer in the production of polymers and resins. It enhances the flexibility and durability of materials, making it valuable in manufacturing PVC products such as cables, flooring, and synthetic leather. Additionally, it serves as an intermediate in organic synthesis, particularly in the production of specialty chemicals and pharmaceuticals. Its compatibility with various polymers also makes it suitable for use in coatings and adhesives, improving their performance and application properties.
