Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to minimize evaporation and oxidation.
