Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place 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.
