Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This compound may be light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under an inert atmosphere such as nitrogen or argon when not in use to prevent degradation and moisture absorption.
