Used primarily as a plasticizer in polymer formulations, this compound enhances flexibility and workability of plastics, especially in polyvinyl chloride (PVC) and related elastomers. It improves low-temperature performance, maintaining material elasticity under cold conditions. Its branched alkyl structure contributes to good solubility in organic matrices and reduces crystallization tendency, making it suitable for applications requiring long-term stability and durability. Commonly found in wire and cable insulation, automotive parts, and flexible films where resistance to migration and extraction is important. Also serves as a secondary plasticizer in combination with primary esters to fine-tune processing characteristics and final product properties.
