Storage

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