Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This hygroscopic (moisture-sensitive) material should be kept in a cool, dry place and allowed to equilibrate to room temperature before opening to prevent condensation. For optimal performance, store under inert atmosphere (e.g., nitrogen or argon) after initial opening.
