Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent absorption of moisture. For long-term storage, consider desiccated conditions.
