Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under a dry inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
