Used as a plasticizer in polymer formulations to improve flexibility and workability of plastics, especially in cellulose-based and vinyl resins. Enhances low-temperature performance and elongation properties without significantly reducing tensile strength. Also serves as a solvent and carrier in coatings, adhesives, and sealants due to its good solvating power and slow evaporation rate. Occasionally utilized in the synthesis of other ester compounds as an intermediate in organic reactions.
