Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from strong bases and reactive metals. Due to its halogenated and fluorinated nature, it should be stored separately from incompatible materials. Handle and store under an inert atmosphere if specified for high-purity grades to prevent degradation.
