 |  | 4-(4-Methoxyphenyl)-2-butanone Usage And Synthesis |  
 | Description | 4-(p-Methoxyphenyl)-2-butanone has an intensely sweet, floral,
fruity odor and a cherry-raspberry flavor at low concentrations. 
May be prepared by condensing acetone with anisaldehyde to yield anisylidene acetone and subsequent hydrogenation in the presence 
of Pd catalyst. |  | Chemical Properties | clear colourless to pale yellow liquid |  | Chemical Properties | 4-(p-Methoxyphenyl)-2-butanone has an intensely sweet, floral,fruity odor and cherry–raspberry flavor at low concentrations. |  | Occurrence | Contained (approximately 53% level) in the odorous principle obtained by extraction and hydrolysis from aloe
wood (Aquilaria algallocha Roxb.) and in anise. |  | Uses | In insect attractants, organic synthesis, flavoring. |  | Uses | 4-(4-Methoxyphenyl)-2-butanone is used as pharmaceutical intermediate. |  | Preparation | By condensing acetone with anisaldehyde to yield anisylidene acetone and subsequent hydrogenation in the presence of
Pd catalyst. |  | Definition | ChEBI: 4-(4-Methoxyphenyl)-2-butanone is a member of methoxybenzenes. |  | Aroma threshold values | Aroma characteristics at 5.0%: sweet, fruity, woody, powdery, honey, vanilla, raspberry and ionone-like. |  | Taste threshold values | Taste characteristics at 40 ppm: floral, woody, ionone, raspberry, fruity, spice and berry. |  | Synthesis Reference(s) | Tetrahedron Letters, 33, p. 951, 1992 DOI: 10.1016/S0040-4039(00)91585-5 |  | Safety Profile | Low oral and skin 
toxicity. A flammable liquid. When heated 
to decomposition it emits acrid smoke and 
irritating fumes. |
