Quality Control

Our 1,1,2,2,3,3,4,4-Octafluorobutane-1-Sulphonic Acid is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay and impurity profiling, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature and strong acid properties, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
