Chemical Information

FooDB Name

2-Undecanone

Description

2-Undecanone, also known as undecan-2-one or rue ketone, 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). 2-Undecanone is a ketone, also known as methyl nonyl ketone (MNK). Like most methyl ketones, 2-undecanone undergoes a haloform reaction when in the presence of a base. For example, the reaction between 2-undecanone and sodium hypochlorite yields sodium decanoate, chloroform, and sodium hydroxide. 2-Undecanone is a very hydrophobic molecule, practically insoluble in water but it is soluble in ethanol, benzene, chloroform, and acetone. 2-Undecanone is found in palm kernel oil and soya bean oil. 2-Undecanone is an important constituent of rue oil (Ruta graveolens) and found in many other essential oils. Also found in black currant buds, raspberry, black berry peach and other fruits. 2-Undecanone is used in flavourings. It is found naturally in bananas, cloves, ginger, guava, strawberries, and wild-grown tomatoes. 2-Undecanone is used in the perfumery and flavoring industries, but because of its strong odor it is primarily used as an insect repellent or animal repellent.

Classification

Description

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.
