Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed and upright. Recommended storage temperature is 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to maximize shelf-life stability.
