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 light-sensitive; containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, amines, and alcohols.
