Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality. Keep away from heat, sparks, and open flame.
