Quality Control

Our Dimethylbromonium Hexafluoroantimonate(1-) is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot undergoes rigorous analytical testing, including NMR and titration methods, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from incompatible materials such as strong bases and reducing agents.
