Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. The container should be kept in a cool, dry, and well-ventilated area separate from incompatible materials. Allow the product to reach room temperature in the sealed container before opening to prevent condensation.
