Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). For long-term storage, consider sealing under an inert gas such as argon or nitrogen and keeping the container in a freezer (-20°C). Keep away from strong oxidizing agents.
