Quality Control

Our Xtalfluor-M is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high performance. Each lot is analyzed to confirm identity, purity, and absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by NMR or titration), water content (KF), and related substances is provided with every shipment to support your quality assurance processes.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) after initial opening to maintain product integrity and prevent decomposition.
