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)]
