Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C (refrigerated) to minimize volatility and maintain stability. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation.
