Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle the material under a dry atmosphere or desiccated conditions to prevent degradation. For long-term storage, maintaining the container at a controlled room temperature (15-25°C) is advised.
