Used primarily as a key intermediate in the synthesis of organic semiconductors and conductive polymers. Its functional hydroxyl and ester groups enable cross-linking and modification for use in electronic materials, particularly in the development of organic field-effect transistors (OFETs) and flexible electronics. Also employed in the preparation of specialty polymers with enhanced thermal stability and charge transport properties. Additionally, it serves as a building block in pharmaceutical research for designing novel heterocyclic compounds with potential biological activity.
