Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. For long-term storage, keep the container sealed under an inert atmosphere or in a desiccator to prevent absorption of moisture and carbon dioxide from the air, which can affect product quality.
