Quality Control

Our Thionyl Fluoride is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by GC and impurity profiling, to ensure it meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed, properly rated cylinder or container, protected from light and moisture. Store in a cool, well-ventilated area, away from heat, ignition sources, and incompatible materials such as strong bases and reactive organics. Due to its highly volatile and reactive nature, storage temperature should be maintained stable, typically at or below ambient temperature. Always use appropriate personal protective equipment and engineering controls when handling.
