Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material should be stored in a cool, dry place, ideally at controlled room temperature (15-25°C). For long-term storage, consider using a desiccator or maintaining the container under an inert atmosphere to prevent moisture uptake, which can affect purity and handling properties.
