| | 1-Phenyl-1,2-propanedione Usage And Synthesis |
| Chemical Properties | clear yellow liquid | | Chemical Properties | 1-Phenyl-1,2-propanedione has a pungent, plastic odor. | | Occurrence | Reported found as a constituent in coffee, baked potato and butter. | | Uses | Pyruvophenone was used in the synthesis of opioid receptor agonists for gastrointestinal disorders. The enantioselective hydrogenation of Pyruvophenone over Pt colloids was also studied. | | Definition | ChEBI: An alpha-diketone that consists of 1-phenylpropane bearing keto substituents at positions 1 and 2. It is found in coffee. | | Aroma threshold values | Aroma characteristics at 1.0%: creamy, buttery, fatty, slightly vanillalike, slightly walnut nutty, almond
and marzipanlike with a woody styraxlike nuance, and having a slightly sour yeasty and fermented nuance. | | Taste threshold values | Taste characteristics at 5 ppm: cultured creamy, dairylike and slightly astringent with a slight spicy caraway/
cumin nuance. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 36, p. 3553, 1971 DOI: 10.1021/jo00822a019 | | General Description | 1-Phenyl-1,2-propanedione is a volatile flavor compound found in khat leaves and cambará honey. | | Synthesis | By oxidation of propiophenone or benzyl methyl ketone with selenium dioxide; by the acid hydrolysis of oximonopropiophenone
or other synthetic routes. |
