Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept tightly sealed in a desiccated environment to prevent moisture uptake, which can compromise stability and reactivity. For long-term storage, consider storage under an inert atmosphere such as argon or nitrogen.
