Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere such as argon or nitrogen to prevent decomposition. Handle and store away from strong acids and organic solvents.
