Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent decomposition.
