Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Due to its hygroscopic and easily oxidized nature, the container must be kept sealed under positive pressure of inert gas. Recommended storage temperature is 2-8°C for long-term stability. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
