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 compound is hygroscopic (moisture-sensitive) and must be handled under a dry, inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
