Hexafluoroacetone is an organic compound with the formula CF3-CO-CF3. It comes in the form of a colourless, hygroscopic, non-flammable, highly reactive gas characterised by a musty odour. The most common form of this substance is hexafluoroacetone sesquihydrate (1.5 H2O). Hexafluoroacetone is a very reactive substance: it will react vigorously with water, forming corrosive acids. In the presence of humidity, reaction of hexafluoroacetone with most metals will generate white fumes of hydrogen gas. Hexafluoroacetone will also undergo violent reactions in the presence of alkali.
