Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or inert atmosphere conditions.
