| | 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. |
