Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is highly volatile and hygroscopic (moisture-sensitive). It must be kept under an inert atmosphere (e.g., nitrogen or argon) and protected from moisture to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents.
