Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and easily oxidized; therefore, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
