Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis. Keep away from heat, open flames, and incompatible materials such as water, alcohols, amines, and strong bases.
