Used as an intermediate in organic synthesis, particularly in the production of plasticizers for polymers. It contributes to improving flexibility and durability of plastics, especially in polyvinyl chloride (PVC) applications. Also utilized in the preparation of specialty resins and coatings due to its reactive carboxylic acid groups and cyclic structure. Its unsaturated ring allows for further chemical modifications, making it valuable in developing performance chemicals and fine chemicals for industrial applications.
