2,5-Furandicarboxylic Acid
Product Overview
2,5-Furandicarboxylic acid (FDCA), CAS 3238-40-2, is a diacid monomer supplied as a white powder. It is the standard renewable building block used with glycols to produce polyethylene furanoate (PEF) and other furan-based polyesters and copolyesters.
Technical Specifications
High purity with assay not less than 99.9% (HPLC), low water content (≤0.5%), and clear dissolution behavior in the specified pyridine solubility check.
| Property | Unit | Value | Standard |
|---|---|---|---|
| Assay (HPLC) | % | 99.98 | Not less than 99.9% |
| Appearance | - | white powder | white powder |
| Pyridine solubility | - | Clear and transparent | Completely dissolved transparent |
| Water | % | 0.17 | <=0.5% |
Applications
FDCA couples with ethylene glycol to yield PEF as a PET-class polyester with bio-based content tied to the furan diacid; it also feeds other specialty polymers, coatings, and chemical derivatives.
Packaging & Storage
Typically supplied in 100 kg units.
Store in cool, dry conditions.
