2, 5- Furandicarboxylic acid (FDCA)
As an aromatic dibasic acid with a scarce rigid structure derived from HMF downstream, FDCA has the same functional group, similar aromaticity, and reactivity with terephthalic acid(PTA), and is considered an ideal substitute and modifier for PTA. The U.S. Department of Energy has identified FDCA as one of the 12 promising biobased platform compounds for building the "green" chemical industry of the future.
