Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and moisture-sensitive nature, this product must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. For solutions, typical recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, oxidizers, and water.
