Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and under an inert atmosphere if necessary to prevent degradation. Keep away from strong bases and incompatible materials.
