Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from strong oxidizing agents.
