Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed to prevent absorption of atmospheric moisture. For long-term storage, consider storage under an inert atmosphere such as nitrogen.
