Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
