2,5-Furandicarboxylic acid (Cat No.:R002978) is a bio-based aromatic diacid featuring two carboxylic acid groups at the 2- and 5-positions of a furan ring. It is widely recognized as a sustainable alternative to terephthalic acid in the production of polyesters such as polyethylene furanoate (PEF), offering superior gas barrier properties and thermal stability. Derived from renewable resources like fructose or hydroxymethylfurfural (HMF), FDCA plays a key role in green chemistry and bioplastic development. It appears as a white crystalline solid, is sparingly soluble in water, and has excellent polymer-forming potential.
