Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts violently with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture. Store away from incompatible materials.
