Used as a plasticizer in polymer formulations to improve flexibility and durability of plastics, especially in polyvinyl chloride (PVC) products such as wires, sheets, tubes, and other flexible items. Enhances low-temperature performance, elongation properties, impact resistance, and transparency without significantly compromising tensile strength. Also serves as a solvent or carrier in coatings, adhesives, and sealants due to its low volatility and good solvating ability. Its alkyl chain structure contributes to improved migration resistance compared to shorter-chain phthalate-based plasticizers. Occasionally utilized in specialty lubricants and as an intermediate in the synthesis of other organic compounds.
