Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon or nitrogen) when opening to prevent degradation. For long-term storage, consider storing under an inert gas blanket in a desiccator.
