Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a dry, cool place. Due to its hygroscopic and easily oxidized nature, the container must be sealed immediately after use to minimize exposure to moisture and air. Keep away from heat and incompatible materials.
