Used primarily as a plasticizer in polymers to enhance flexibility and workability, especially in coatings, adhesives, and sealants. Its long alkyl chains improve compatibility with hydrophobic matrices and contribute to good water resistance and low-temperature performance. Also functions as a solvent or carrier in cosmetic formulations due to its low volatility and mild skin compatibility. Occasionally employed in specialty lubricants and as an intermediate in organic synthesis where a masked diacid with lipophilic character is needed.
