Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at 2-8°C (refrigerated) or as specified on the label. Keep away from heat, sparks, and open flames. Containers should be kept tightly sealed when not in use to prevent evaporation and potential concentration of peroxides.
