Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept in a desiccated environment to prevent absorption of water and carbon dioxide from the air. Keep away from strong acids and strong oxidizing agents.
