Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, keep container tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, or at controlled room temperature for short-term use. Keep away from strong oxidizing agents.
