Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, it is recommended to handle and store under an inert atmosphere such as nitrogen or argon for long-term stability. Keep away from heat and incompatible materials.
