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 light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to exclude moisture. Keep away from incompatible materials.
