| Common Name | 3-Buten-2-one |
|---|
| Description | 3-Buten-2-one, also known as 2-butenone or acetyl ethylene, belongs to the class of organic compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR'. Thus, 3-buten-2-one is considered to be an oxygenated hydrocarbon lipid molecule. 3-Buten-2-one, also called methyl vinyl ketone, is the organic compound with the formula CH3CCH=CH2. It is a reactive compound classified as an enone, in fact the simplest example thereof. It is a useful intermediate in the synthesis of other compounds. 3-Buten-2-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, 3-Buten-2-one has been detected, but not quantified in, several different foods, such as radish (var.), sour cherries, tamarinds, horseradish, and caraway. This could make 3-buten-2-one a potential biomarker for the consumption of these foods. It is a colorless, flammable, highly toxic liquid with a pungent odor. It is soluble in water and polar organic solvents. |
