1. 🚀 As a core monomer for polymer materials:

• Polyester materials: Polyethylene furandicarboxylate (PEF), polymerized with ethylene glycol, is a current research hotspot. PEF surpasses traditional petroleum-based polyester PET in gas barrier properties (such as oxygen and carbon dioxide) and thermodynamic performance, making it ideal for manufacturing high-performance packaging materials such as beverage bottles and food films, effectively extending shelf life.

• Polyamides: It can be used to synthesize novel bio-based polyamides (commonly known as nylon). These materials typically possess excellent thermal stability and mechanical properties and can be used in fields such as engineering plastics. Its derivative, tetrahydrofuran-2,5-dicarboxylic acid (THFDCA), can be used to synthesize polyamides with high water absorption.

• Other polymers: FDCA can also be used to synthesize polyurethanes, unsaturated resins, and as a plasticizer. Its flexible derivative, THFDCA, can replace petroleum-based raw materials in the manufacture of thermoplastic polyesters and elastomers, with potential applications in automotive, protective equipment, and clothing industries.

2. 🧪 Applications in the pharmaceutical field:
FDCA is a key raw material for synthesizing intermediates of certain antibacterial drugs. Furthermore, it is itself listed as an “endogenous human metabolite,” giving it value in pharmaceutical research.

3. ✨ Other cutting-edge and potential applications:

• Metal-organic frameworks (MOFs): FDCA can be used as an organic linker to synthesize MOF materials with specific pore structures. These materials have applications in gas adsorption, separation, and catalysis.

• High-performance fibers: FDCA is a potential monomer for the preparation of high-performance fibers such as aramid fibers.
