2,5-Furandicarboxylic Acid
Odor: characteristic
Use: 2,5-furandicarboxylic acid (FDCA) is listed in a 2004 US Department of Energy National Renewable Energy Laboratory (NREL) report as one of the top twelve building blocks that can be subsequently converted to a number of high-value bio-based chemicals or materials. Derivatives of furan produced from renewable carbohydrates are the main types of next generation platform chemicals. FDCA made from bio-based 5-HMF (5-hydroxymethylfurfural) plays a particularly important role and opens, amongst others, the door to the multi-billion bio-based packaging market. FDCA is the oxidation product of both primary alcohol and aldehyde groups of 5-HMF to carboxylic acid groups and is considered to be the most important derivative of 5-HMF. This sugar based compound is a potential replacement of terephthalic acid, which is a monomer, used in polyethylene terephthalate (PET) plastics. Amongst others, FDCA is the basis for 100% bio-based PEF (polyethylene furanoate) bottles, fibres or films.

2,5-Furandicarboxylic acid is a normal urinary metabolite in humans. (PMIDs 14708889, 8087979, 2338430, 3711221) Dietary studies show that the furan derivatives or their precursors are of exogenous origin. They are originated from furan derivatives found in food prepared by strong heating. This may explain the absence of 2,5-furandicarboxylic acid in urine of breastfed children, and the absence of these acids in the urine of rat, pig, cow, ox, rabbit, and monkey. (PMID 4630229) [HMDB]
