Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place, ideally under an inert atmosphere such as argon or nitrogen in a glovebox or desiccator. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
