Trifluoromethyl hypofluorite is an organofluorine compound with the formula CF 3OF. It exists as a colorless gas at room temperature and is highly toxic. It is a rare example of a hypofluorite (compound with an O−F bond). It is prepared by the reaction of fluorine gas with carbon monoxide: 2 F2 + CO → CF3OF WebJul 11, 2024 · Lethal concentration 50 (LC50) and lethal dose 50 (LD50) are both parameters used to quantify the toxicity of a substance. Both indicate the concentration …
