Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents. Use appropriate corrosion-resistant equipment for handling.
