Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and strictly light-sensitive nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, and well-ventilated area. Keep away from moisture, acids, and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability.
