Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize decomposition. Ideal storage temperature is between 2°C and 8°C (refrigerated) for optimal stability.
