Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, consider storage under an inert atmosphere (e.g., nitrogen or argon) in a desiccator. Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture.
