Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this product must be stored under a dry, inert atmosphere (argon or nitrogen) in a cool, well-ventilated area, away from heat and ignition sources. Recommended storage temperature is 2-8°C for extended stability. Keep away from moisture, strong acids, and oxidizing agents.
