Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; it must be stored under an inert atmosphere (e.g., argon or nitrogen) in a sealed container to prevent degradation. Keep away from incompatible materials.
