Product Description:
2,5-Furandicarboxylic acid (FDCA) is a bio-based aromatic dicarboxylic acid, typically appearing as a white to light-yellow crystalline powder. It is recognized as a key platform chemical, often derived from renewable resources like C6 sugars. FDCA is primarily valued as a monomer for producing advanced polymers, most notably polyethylene furanoate (PEF), a sustainable alternative to petroleum-based plastics like PET, offering enhanced barrier properties.

Product Usage:
Polymer Synthesis (Primary Use): Serves as a crucial monomer for the production of polyethylene furanoate (PEF), a bio-based polyester with superior gas barrier properties (O₂, CO₂, H₂O) compared to PET, making it ideal for food and beverage packaging (e.g., bottles, films).
Other Polyesters and Polyamides: Used to synthesize various other furan-based polyesters, polyamides, and polyurethanes, imparting unique thermal, mechanical, and barrier properties.
Plasticizers: Can be esterified to produce furan-based plasticizers as potential bio-based alternatives to phthalate plasticizers.
Resins and Coatings: Incorporated into resins and coatings to enhance their performance characteristics.
Pharmaceutical Intermediates: Investigated as a building block for certain pharmaceutical compounds and fine chemicals.
Fungicides: Shows potential in the development of antifungal agents.
Chelating Agents: Its dicarboxylic acid structure allows it to act as a chelating agent for metal ions.
