Product Description of 2,5-Furandicarboxylic Acid CAS#3238-40-2
First documented by Fittig and Heinzelmann back in 1876, 2,5-furandicarboxylic-acid belongs to the family of furan-based derivatives. This high-stability synthetic precursor possesses outstanding chemical activity for diverse synthetic workflows.
This raw-material dissolves in aqueous alkali-based solutions. When the surrounding environment keeps acidic, the substance presents itself as fine white powder. It ranks as an essential monomer for manufacturing plastics with excellent anti-corrosion performance.
Users need to take protective measures during manipulation. The substance is capable of triggering skin, eye and respiratory-tract irritation owing to its inherent chemical traits.
