Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile, easily oxidized, and hygroscopic nature, this compound must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C to minimize degradation and maintain stability. Containers must be kept tightly sealed to prevent moisture ingress and oxidation.
