Used as a bio-based platform chemical in the production of sustainable polymers, particularly as a renewable alternative to petroleum-derived terephthalic acid. It serves as a key intermediate in synthesizing polyesters and polyamides with potential applications in packaging, textiles, and engineering plastics. Its furan ring structure enables the development of high-performance bioplastics with improved thermal and mechanical properties. Also investigated for use in renewable solvents and as a precursor in fine chemical synthesis.
