Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this product must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C to maximize shelf life and stability. Handle and open containers only in a controlled, moisture-free environment such as a glovebox.
