Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere), hygroscopic (moisture-sensitive), and highly volatile, this material must be stored under a dry, inert gas (argon or nitrogen) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials.
