Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and highly volatile nature, store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). The container must be kept tightly sealed under an inert atmosphere to minimize moisture absorption and degradation. Keep away from incompatible materials such as strong acids and oxidizers.
