| | ETHYL UNDECANOATE Usage And Synthesis |
| Chemical Properties | CLEAR COLOURLESS LIQUID | | Chemical Properties | Ethyl undecanoate has a coconut-like odor | | Occurrence | Reported found in apple, butter, grape, brandy, wheat bread, rum, whiskey, wine, cognac, butter, plum brandy
and sake. | | Uses | Ethyl undecanoate was used to prepare the corresponding aldehyde in the presence of Lithium diisobutyl-t-butoxyaluminum hydride (LDBBA). | | Definition | ChEBI: Ethyl undecanoate is a fatty acid ester. | | Preparation | By reduction of the l-undecen-ll-oic acid ethyl ester with hydrogen in the presence of Ni at 180°C; or by direct esterification of n-undecanoic acid with ethyl alcohol under reflux. | | Aroma threshold values | Aroma characteristics at 1.0%: rum-like, estry, fatty and waxy, soapy with creamy nuances. | | Taste threshold values | Taste characteristics at 15 ppm: cheesy, buttery, creamy, rum and cognac-like, with fruity apple and banana
nuances. Taste characteristics at 25 ppm: waxy, creamy, slight fruity with coconut and cherry nuance. | | Synthesis Reference(s) | Tetrahedron Letters, 30, p. 689, 1989 DOI: 10.1016/S0040-4039(01)80283-5
Chemical and Pharmaceutical Bulletin, 43, p. 2075, 1995 DOI: 10.1248/cpb.43.2075 | | General Description | Ethyl undecanoate is a volatile fatty acid ethyl ester (FAEE) commonly found in alcoholic beverages. It is also reported to occur in fermented wheat germ extract. |
