Quality Control

Our 1H,1H-Heptafluorobutyl Nonafluorobutanesulfonate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (¹H, ¹⁹F), HPLC, and Karl Fischer titration to ensure identity, purity, and moisture content meet stringent specifications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong bases and reducing agents.
