Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider maintaining under an inert gas atmosphere such as nitrogen to preserve product integrity.
