Quality Control

Our Benzoylium Hexafluoroantimonate is manufactured under stringent process controls to ensure batch-to-batch consistency and high reactivity. Each lot undergoes comprehensive analytical testing, including assay by titration and identification by FT-IR and NMR spectroscopy, to verify chemical identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored under a dry, inert atmosphere (e.g., argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C. The container should be kept in a well-ventilated area, away from incompatible materials such as strong bases and oxidizing agents.
