| 3-Hydroxy-4-methyl-5-ethyl-2(5H)furanone Usage And Synthesis |
| Chemical Properties | light yellow liqui |
| Chemical Properties | Abhexone has been found in, for example, lovage and roasted coffee. It has a bouillon-like, coffee and lovage aroma, depending on its concentration. It can be prepared starting from alkyl 2-oxobutanoate either by self-condensation followed subsequently by decarbomethoxylation or by condensation with propionaldehyde and subsequent cyclization . Alkyl 2-oxobutanoate is available from acrylaldehyde and sodium cyanide via alkyl 2-hydroxy-3-butenoate or by reaction of dialkyloxalate with ethyl magnesium bromide . It is used for aromatization of food. |
| Chemical Properties | 5-Ethyl-3-hydroxy-4-methyl-2(5H)-furanone has a sweet, maple, caramel odor. |
| Occurrence | Reported found in coffee. |
| Taste threshold values | Taste characteristics at 50 ppm: sweet, fruity with brown maple note. |
