Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and alkali metals. Recommended storage temperature is between 2°C and 8°C to maintain optimal stability for extended periods. The container should be kept upright and sealed under an inert atmosphere (e.g., nitrogen or argon) if opened, due to potential sensitivity to moisture and oxygen.
