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 must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
