Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and easily oxidized; it must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to minimize moisture ingress.
