Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container tightly sealed under an inert gas blanket (e.g., nitrogen) and at controlled room temperature (15-25°C).
