2,5-Furandicarboxylic acid (FDCA) is an organic chemical compound consisting of two carboxylic acid groups attached to a central furan ring. It was first reported as dehydromucic acid by Rudolph Fittig and Heinzelmann in 1876, who produced it via the action of concentrated hydrobromic acid upon mucic acid . [ 2 ]

[2] [3] As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). PEF has been described in (patent) literature since 1951, [ 4 ] but has gained renewed attention since the US department of energy proclaimed its building block, FDCA, as a potential bio-based ...
After the FDA has banned red dye No.3, you may be wondering which drinks and candies contain it. Here's the full list—plus, when it'll be removed from shelves.
The petition filed by over 20 consumer advocacy groups in 2022 that argued for the removal of Red Dye No. 3 from food and dietary supplements cited studies, the FDA's prior use of the Delaney ...
2,5-Furandicarboxaldehyde (FDC) is an organic compound with the molecular formula C 4 H 2 O(CHO) 2. It consists of a furan ring with aldehyde groups on the 2 and 5 position. It is therefore classified as a dialdehyde .

Of these the most important is 2,5-furandicarboxylic acid, which has been proposed as a replacement for terephthalic acid in the production of polyesters. [20] [21] HMF can be converted to 2,5-dimethylfuran (DMF), a liquid that is a potential biofuel with a greater energy content than bioethanol. Hydrogenation of HMF gives 2,5-bis(hydroxymethyl ...
