Used primarily as a plasticizer in the production of cellulose ester plastics, enhancing flexibility and workability. It improves the durability and resilience of films and coatings, making it suitable for use in adhesives, printing inks, and encapsulation materials. Also employed in controlled-release formulations in pharmaceuticals due to its biocompatibility and ability to form stable matrices. Its solubility characteristics make it useful in certain specialty solvent applications.
