Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place, ideally at 15-25°C, under an inert atmosphere such as argon or nitrogen for long-term stability. Keep the container tightly sealed when not in use to prevent degradation from atmospheric moisture.
