| | 1-(4-Methoxyphenyl)-1-penten-3-one Usage And Synthesis |
| Description | 1 -(p-Methoxypheny 1)-1 -penten-3-one has an odor similar to butter,
sweet and lasting. It has a sweet, fruity taste at low levels and a
slightly burning taste at higher levels. Prepared by saturation at
room temperature of a mixture of anisaldehyde and methyl ethyl
ketone with HCL, or by treating α-methyl-α-(4-hydroxy)benzylidene acetone with methyl iodide in alkaline solution. | | Chemical Properties | 1-(p-Methoxyphenyl)-1-penten-3-one has an odor similar to butter. It has a sweet, fruity taste at low levels and slightly
