Quality Control

Our 9H-Xanthene-9-Carbonyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for assay and purity determination, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
