Used primarily as a plasticizer intermediate in the production of polymers, enhancing flexibility and workability of plastics. It is also employed in the synthesis of specialty esters for lubricants and coatings, where it contributes to thermal stability and resistance to oxidation. Its branched ester structure improves low-temperature performance in lubricating formulations. Additionally, it serves as a building block in organic synthesis for fine chemicals and fragrances due to its reactivity and solubility characteristics.
