PROPENYL GUAETHOL exists in (Z)- (mp 35–36°C), [876306-58-0], and in (E)-
(mp 86°C), [63477-41-8] forms. The (E)-isomer has a sweet vanilla-like odor.
Propenylguethol can be prepared from isosafrole by reaction with
methylmagnesium chloride or by ethylation of isoeugenol followed by selective
demethylation with alkali . | [Chemical Properties]
Propenylguaethol has a vanilla-like odor and flavor. | [Definition]
ChEBI: 2-Ethoxy-5-(1-propenyl)phenol is an aromatic ether. | [Preparation]
By alkaline hydrolysis of 1-ethoxy-2-methoxy-4-propenyl benzene in ethanol or methanol solution at 150 to 190°C under
pressure; or in ethylene glycol solution at the same temperature under atmospheric pressure; by saponification and contemporary
transposition of the double bond starting from 1-ethoxy-2-methoxy-4-allyl benzene. | [Aroma threshold values]
Detection: 400 ppb. Aroma characteristics at 1.0%: vanilla, sweet, spicy, slightly phenolic with a heliotropine-
like creaminess. | [Taste threshold values]
Taste characteristics at 25 ppm: vanilla, spicy, sweet nutty, anisic with a biting creaminess. | [Synthesis Reference(s)]
