Storage

Preserve in a tightly closed container, protected from light. Due to its sensitivity to oxidation, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) 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 condensation.
