Common Name | Cyclopentanone |

Description | Cyclopentanone belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Cyclopentanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, cyclopentanone is considered to be an oxygenated hydrocarbon lipid molecule. Cyclopentanone is a cyclic ketone, structurally similar to cyclopentane, consisting of a five-membered ring containing a ketone functional group. Cyclopentanone is a colorless liquid organic compound with a peppermint-like odor. Cyclopentanone is found in various foods, including potato and tomato, and cooked foods, e.g. butter, meats, coffee, roasted peanut. Cyclopentanone is also used as a flavouring ingredient. |
