Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Keep the container in a cool, dry, well-ventilated place away from incompatible materials.
