Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to minimize volatility and degradation. Keep away from heat, sparks, open flames, and oxidizing agents.
