Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, oxidizing agents, and alcohols.
