Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 2-8°C or as specified on the label. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flame.
