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). This material is hygroscopic (moisture-sensitive) and reacts with water and strong bases; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis. Keep away from heat, open flames, and incompatible materials such as strong oxidizers, bases, and alcohols.
