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 hygroscopic (moisture-sensitive) and reacts violently with water, releasing hydrogen chloride. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) and separated from strong acids, bases, and oxidizing agents.
