Quality Control

Our Potassio[2,5-Dioxo-3,4-Bis(Dicyanomethylene)-1-Potassiocyclopentyl]Methanedicarbonitrile is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key specifications such as assay (HPLC), impurity profile, and moisture content. Our quality commitment supports research and scale-up processes where reliable material properties are essential.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
