Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and strictly light-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is between 2°C and 8°C. The container should be kept tightly sealed and allowed to reach room temperature before opening to minimize moisture ingress.
