Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). The compound may be hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed under an inert atmosphere if necessary. Keep away from strong oxidizing agents.
