Beschreibung
Isoeugenol has a floral odor reminiscent of carnation. May be prepared by the alkaline isomerization of eugenol obtained from essential oils high in eugenol.
Chemische Eigenschaften
Isoeugenol occurs in many essential oils, mostly with eugenol, but not as the main component. Commercial isoeugenol is a mixture of (E)- and (Z)-isomers, in which the (E)-isomer dominates because it is thermodynamically more stable. Isoeugenol is a yellowish, viscous liquid with a fine clove odor, with that of the crystalline trans-isomer being the more delicate.
Isoeugenol can be hydrogenated catalytically to form dihydroeugenol. Vanillin was formerly prepared by oxidation of isoeugenol. Additional fragrance materials are prepared by esterification or etherification of the hydroxy group.

Chemische Eigenschaften
light yellow-green viscous liquid
Chemische Eigenschaften
Isoeugenol has a floral odor reminiscent of carnation.
Occurrence
The commercial product is a mixture of cis- and trans-isomers; reported found in the essential oils of ylangylang and nutmeg; also in the oil from flowers of Michelia champaca and in the oil from seeds of Nectandra puchury. Reported found in bilberry, guava, blackberry, tomato, cinnamon, clove bud and stem, nutmeg, mace, thymus, tea, coffee, fatty fish, beer, rum, plum, mushroom, dill, malt wort, elder flower, cuttlefish, Chinese quince, pimento leaf and maté.
Verwenden
Isoeugenol may be used as an analytical reference standard for the determination of the analyte in bioconversion broth using reversed-phase high-performance liquid chromatography with ultraviolet detection (RP-HPLC-UV).
Verwenden
Isoeugenol is used inmanufacture of vanillin; perfumes; flavoring; fragrance in perfumery, over-the-counter medicines, dental materials, foods; some perfumery uses (soap gardenia; coffee; abronea; tuberose; jonquil); natural occurrence (nutmeg oil).
Verwenden
isoeugenol is a volatile oil fraction derived from eugenol. It is also found in ylang-ylang and nutmeg oils. It is used in cosmetics as a fragrance or to mask odor.
synthetische
The starting material for the synthesis of isoeugenol is eugenol.The sodium or potassium salt of eugenol is isomerized to isoeugenol by heating. Isomerization can also be achieved catalytically in the presence of ruthenium [346] or rhodium compounds.
Definition
ChEBI: A phenylpropanoid that is an isomer of eugenol in which the allyl substituent is replaced by a prop-1-enyl group.
Aroma threshold values
Detection: 100 ppb
Taste threshold values
Taste characteristics at 10 ppm: sweet spice and clove with woody and phenolic nuances.
Allgemeine Beschreibung
Pale yellow oily liquid with a spice-clove odor. Freezes at 14°F. Density 1.08 g / cm3. Occurs in ylang-ylang oil and other essential oils.
Air & Water Reaktionen
Slightly water soluble .
Brandgefahr
ISOEUGENOL is combustible.
Kontakt-Allergie
Isoeugenol is a mixture of two cis and trans isomers. It occurs in ylang-ylang and other essential oils. It is a common allergen of perfumes and cosmetics such as deodorants and is contained in fragrance mix. Its presence in cosmetics is indicated in the INGREDIENTS series. Substitution by esters such as isoeugenyl acetate (not indicated on the package) does not always resolve the allergenic problem, because of the in vivo hydrolysis of the substitute into isoeugenol.
Synthese
By the alkaline isomerization of eugenol obtained from essential oils high in eugenol.
