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); ensure the container is sealed under an inert atmosphere or in a desiccated environment after opening to prevent degradation. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture ingress.
