Quality Control

Our Nonafluorobutane-1-Sulfonic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets the high-purity standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
