Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent, it should be stored separately from incompatible materials such as strong bases and oxidizing agents. Containers should be kept tightly sealed when not in use to minimize moisture uptake and volatilization.
