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. 2-Hendecanone 2-Oxoundecane Enodyl FEMA 3093 Ketone, methyl nonyl Luparone Methyl n-nonyl ketone Methyl nonyl ketone Methyl-n-nonylketone Methylnonylketone MGK dog &amp MGK dog AMP mnk MNK Nonyl methyl ketone Rue ketone Undecan-2-one Undecanone Undecanone-(2) C11H22O 170.2918 170.167065326 undecan-2-one undecan-2-one 112-12-9 CCCCCCCCCC(C)=O InChI=1S/C11H22O/c1-3-4-5-6-7-8-9-10-11(2)12/h3-10H2,1-2H3 KYWIYKKSMDLRDC-UHFFFAOYSA-N 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.
