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 must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original packaging to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
