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 material is hygroscopic (moisture-sensitive) and must be kept under inert atmosphere or in a desiccator after opening to prevent degradation. Keep away from incompatible materials such as strong bases and reducing agents.
