Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (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) when not in use to prevent degradation. Keep away from heat and incompatible materials.
