Used primarily as a plasticizer in polymers to enhance flexibility and workability, especially in polyvinyl chloride (PVC) and other resin systems. It improves low-temperature performance, making materials less brittle in cold environments. Commonly found in flexible cables, automotive parts, and synthetic leather due to its good solubility and compatibility with various organic compounds. Also serves as a lubricant base in specialty applications where low volatility and moderate stability are required.
