Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C. Allow the sealed container to reach room temperature before opening to minimize moisture ingress and pressure changes.
