Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere (e.g., argon or nitrogen) for long-term storage to prevent oxidation.
