Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere such as argon or nitrogen for long-term storage to prevent surface oxidation. Keep away from strong acids and strong oxidizing agents.
