Common Name | Undecane |

Description | Undecane, also known as CH3-[CH2]9-CH3 or hendekan, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, undecane is considered to be a hydrocarbon lipid molecule. Undecane may also be used as an internal standard in gas chromatography when working with other hydrocarbons. For example, if one is working with a 50 m crosslinked methyl silicone capillary column with an oven temperature increasing slowly, beginning around 60 °C, an 11-carbon molecule like undecane may be used as an internal standard to be compared with the retention times of other 10-, 11-, or 12- carbon molecules, depending on their structures. Undecane is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. undecane has been detected, but not quantified, in cardamoms. This could make undecane a potential biomarker for the consumption of these foods. Since the boiling point of undecane (196 °C) is well known, it may be used as a comparison for retention times in a gas chromatograph for molecules whose structure has been freshly elucidated. It has 159 isomers. It is used as a mild sex attractant for various types of moths and cockroaches, and an alert signal for a variety of ants. |
