Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept tightly sealed in a desiccator to minimize exposure to air and moisture.
