Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and easily oxidized nature, this material must be stored and handled under an inert atmosphere (argon or nitrogen). Store in a cool, dry, well-ventilated area away from heat, ignition sources, and incompatible materials such as strong oxidizing agents. Recommended storage temperature is 2-8°C for extended stability.
