Quality Control

Our Perfluoro-3-Oxapentan-1,5-Disulfonic Acid Hexahydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by titration or HPLC), water content (KF), and impurity profiles are available upon request. We adhere to relevant industry standards for high-purity chemical intermediates.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
