Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain stability.
