| Hazard Information | Back Directory | [Chemical Properties]
clear colorless to pale yellow liquid | [Definition]
ChEBI: A fenchone that has 1S,4R stereochemistry. A colourless, oily liquid found in fennel oil, it is used in perfumery and as flavour in foods. | [Uses]
As flavor in foods; in perfumes. | [Description]
d-Fenchone has a camphor-like odor, powerful and sweet, and a warm, somewhat bitter, burning taste. d-Fenchone is isolated from cedarleaf oil (thuja oil).
| [Occurrence]
Reported found in several essential oils: Thuja plicata, Thuja occidentalis, Thuja standishii, Russian anise, fennel, a few Artemisia varieties (A frigida, A verlotorum, A santolinaefolia), Lavanda stoechas, Lavanda burmannii, and others; the highest levels are found in fennel oil (12 to 19%); two optically active forms have been isolated Also reported found in basil, caraway, cedar leaf oil, cloves, dill, licorice and thyme | [Preparation]
Isolated from cedarleaf oil (thuja oil). | [Aroma threshold values]
Detection: 510 ppb; aroma characteristics at 1.0%: cooling camphoreous, terpy, spicy, sweet mentholic pine-like. | [Taste threshold values]
Taste characteristics at 5 ppm: cooling camphoreous, with green citrus lime nuances. | [General Description]
Produced and qualified by HWI pharma services GmbH.
Exact content by quantitative NMR can be found on the certificate. | [Purification Methods]
The oily liquid is purified by distillation in a vacuum and is very soluble in EtOH and Et2O. [Boyle et al. J Chem Soc, Chem Commun 395 1971, Hückel Justus Liebigs Ann Chem 549 186 1941, (±)-isomer: Braun & Jacob Chem Ber 66 1461 1933.] It forms two oximes, cis-oxime: m 167o (crystallises from pet ether) [] D +46.5o (c 2, EtOH), O-benzoyloxime m 81o, [] D +49o |
