Chemische Eigenschaften
colourless to light yellow liquid
Occurrence
Reported in the essential oils of Myrtaceae and Luraceae; it was identifed originally in the essential oil from roots of Asarum europaeum L and Asarum canadense L Subsequently, it was identifed as the main constituent of the oil from wood of Dacrydium franklinii Hook (97 5%), in Melaleuca bracteata F v M (leaves, 90 to 95%), in Cinnamomum oliveri Bail (leaves, 90 to 95%), and as a minor constituent in the oils of betel, citronella, Japanese calamus, pimenta, hyacinth, rose, basil, bay, cajeput and others Reported found in heated blackberry, pepper, lovage seed, chervil, lemon balm, alpinia species, clove buds, nutmeg, pepper, mace, tarragon, Ocimum sanctum, laurel, myrtle leaf and berry, rosemary, pimento berry and mastic gum leaf oil
Verwenden
Methyl eugenol may be used as an analytical reference standard for the quantification of the analyte in the following:
- Essential oil of Pimenta pseudocaryophyllus using high-performance liquid chromatography (HPLC). The purity of the extracted compound is then determined by gas chromatography coupled to flame ionization detector (GC/FID).
- Stem bark of Cinnamomum zeylanicum Blume using reversed-phase high-performance liquid chromatography (RP-HPLC) with UV-visible detection.
- Rosa hybrida using gas-chromatography coupled to mass spectrometry (GC-MS) technique.
synthetische
Usually prepared by methylation of eugenol.
Allgemeine Beschreibung
Clear colorless to pale yellow liquid with a spicy earthy odor. Bitter burning taste.
Air & Water Reaktionen
Insoluble in water.
Reaktivit?t anzeigen
Methyl eugenol is incompatible with strong oxidizers . May react exothermically with reducing agents to release hydrogen gas.
Hazard
Possible carcinogen.
Brandgefahr
Methyl eugenol is combustible.
Sicherheitsprofil
Confirmed carcinogen. Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. A skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. Some other alkenylbenzenes have carcinogenic activity. See also EUGENOL, ALLYL COMPOUNDS, and ETHERS
m?gliche Exposition
Methyl eugenol is a naturally occurring substance found in the essential oils of several plant
species. Methyleugenol is used as a flavoring agent in jellies, baked goods, nonalcoholic beverages, chewing gum,
candy, pudding, relish, and ice cream. Methyleugenol has
been used as an anesthetic in rodents. It also is used as an
insect attractant in combination with insecticides.
Carcinogenicity
Methyleugenol is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
Solubility in organics
Soluble in alcohol and oils

l?uterung methode
Recrystallise the ether from hexane at low temperature and redistil it (preferably in vacuo). [Hillmer & Schorning Z Phys Chem [A] 167 407 1934, Briner & Fliszár Helv Chim Acta 42 2063 1959, Beilstein 6 H 963, 6 IV 6337.]
Inkompatibilit?ten
Methyleugenol is Incompatible with
strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from
alkaline materials, strong bases, strong acids, oxoacids,
epoxides. Contact with reducing agents may cause the
release of hydrogen gas
Waste disposal
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed.
