Used primarily as a plasticizer in polymers to enhance flexibility and workability, especially in PVC and other resin systems. It improves low-temperature performance and contributes to better UV stability in coatings and films. Also employed in cosmetic formulations and personal care products as a solvent or fragrance carrier due to its mild odor and low volatility. Additionally, it serves as an intermediate in the synthesis of other esters and organic compounds in industrial chemistry.
