Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under an inert atmosphere if specified. Keep away from strong acids, bases, and oxidizing agents.
