Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere or in a desiccator to prevent decomposition. Keep away from incompatible materials such as strong bases and organic compounds.
