Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature and reactivity as a fluoride/strong alkali, it should be kept separate from incompatible materials. Recommended storage temperature is 2-8°C for extended stability. Containers must be kept tightly sealed under an inert atmosphere to prevent moisture ingress and degradation.
