Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials such as water, alcohols, strong acids, and oxidizing agents.
