Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong bases and moisture.
