Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere such as nitrogen or argon to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
