Quality Control

Our Dicesium Carbonylpentachloroosmate(2-) is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including FT-IR spectroscopy for structural confirmation and elemental analysis (C, H, Cl, Os) to verify composition. A detailed Certificate of Analysis (COA) documenting purity, identity, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
