97-54-1CC=Cc1ccc(O)c(OC)c1BJIOGJUNALELMI-UHFFFAOYSA-NIsoeugenol is a commonly used fragrance added to many commercially available products, and occurs naturally in the essential oils of plants such as ylang-ylang. It is also a significant dermatologic sensitizer and allergen, and as a result has been restricted to 200 p.p.m. since 1998 according to guidelines issued by the fragrance industry. Allergic reactivity to Isoeugenol may be identified with a patch test.

用途花精油用香料
説明Isoeugenol has a floral odor reminiscent of carnation. May be prepared by the alkaline isomerization of eugenol obtained from essential oils high in eugenol.
天然物の起源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.
使用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.
一般的な説明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.
製造方法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.

97-54-1DTXSID7022413CHEMBL2135887化学的特性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.Isoeugenol can be hydrogenated catalytically to form dihydroeugenol.
