Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to handle and store under an inert atmosphere for long-term preservation. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
