Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C. This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Allow the container to reach ambient temperature before opening to prevent moisture condensation.
