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 light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
