Used as a plasticizer in polymers to improve flexibility and durability, particularly in coatings and resins. Enhances solubility and compatibility in dye formulations for textiles and inks. Employed in the synthesis of specialty polyesters and optical brighteners due to its aromatic structure and ester reactivity. Also serves as an intermediate in the production of liquid crystals and electronic materials. Its low volatility makes it suitable for applications requiring thermal stability.
