Quality Control

Our Nonafluorobutanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for advanced industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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, 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 prevent moisture absorption, which can affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
