Use
2,5-Furandicarboxylic acid CAS 3238-40-2 has a large potential as a replacement for terephthalic acid, a widely used component in various polyesters, such as polyethylene terephthalate (PET) and polybutyleneterephthalate (PBT). PET has a market size approaching 4 billion lb/yr, and PBT is almost a billion lb/yr. The market value of PET polymers varies depending on the application, but is in the range of $1.00 – 3.00/lb for uses as films and thermoplastic engineering polymers. The versatility of FDCA is also seen in the number of derivatives available via relatively simple chemical transformations. Selective reduction can lead to partially hydrogenated products,such as 2,5-dihydroxymethylfuran, and fully hydrogenated materials, such as 2,5-bis(hydroxymethyl)tetrahydrofuran. Both of these latter materials can serve as alcohol components in the production of new polyester, and their combination with FDCA would lead to a new family of completely biomass-derived products. Extension of these concepts to the production of new nylons, either through reaction of FDCA with diamines, or through the conversion of FDCA to 2,5-bis(aminomethyl)tetrahydrofuran could address a market of almost 9 billion lb/yr, with product values between $0.85 and 2.20/lb, depending on the application. FDCA can also serve as a starting material for the production of succinic acid, whose utility is elsewhere.

Toxicity assays – EU comments on the safety of 2,5-furandicarboxylic acid for food contact materials
The EU Food Safety Authority issued an opinion on the safety assessment of 2,5-furandicarboxylic acid for food contact materials. After 90 days of oral toxicity evaluation of the mice, it was found that the NOAEL level was 300 mg FDCA/kg bw/day without significant damage. The EU expert group believes that 2,5-furandicarboxylic acid does not pose an accumulation risk in humans. When 2,5-furandicarboxylic acid is used to produce a monomer of polyethylene furanate polymer (PEF), the substance itself migrates into the food.
The amount does not exceed 5 mg/kg, and the amount of oligomers below 1000 Da that migrates into food does not exceed 50/zg/kg, which poses no threat to consumers.
