Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert gas blanket (e.g., nitrogen or argon) to minimize potential oxidation. Keep away from strong oxidizing agents and incompatible materials.
