Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
