Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) and away from incompatible materials. Keep the container tightly sealed when not in use to prevent degradation from atmospheric moisture.
