Used as a key building block in the synthesis of advanced polymers, particularly in the production of furan-based polyesters and polyamides. These materials are valued for their biobased origin and potential use in sustainable plastics, fibers, and packaging. It enables the creation of high-performance polymers with good thermal and mechanical properties, suitable for engineering plastics and films. Also explored in pharmaceutical intermediates and covalent organic frameworks (COFs) due to its reactive acid chloride groups and rigid aromatic structure. Its role in condensation reactions makes it useful for developing novel functional materials in research and industrial applications.
