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). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to exclude moisture. For long-term storage, consider the use of desiccants or an inert atmosphere.
