Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment. For extended storage under an inert atmosphere such as argon or nitrogen is recommended to prevent oxidation. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture condensation.
