Quality Control

Every batch of Furan-2,3,4,5-Tetracarboxylic Acid is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards through rigorous analytical controls, including HPLC for purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and product integrity for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
