Quality Control

Our Dichloro(Phenyl)Methylium Hexachloroantimonate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) documenting comprehensive testing are available for all shipments. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). 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.
