94-86-0 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 94-86-0 differently. You can refer to the following data:
1. Free-flowing, white powder; odor and
taste similar to vanilla, but much more powerful.Very soluble in fats, edible solvents,
and essential oils; very slightly soluble in water.
2. 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 .
3. Propenylguaethol has a vanilla-like odor and flavor.
Uses
Different sources of media describe the Uses of 94-86-0 differently. You can refer to the following data:
1. trans-2-Ethoxy-5-(1-propenyl)phenol was used in the synthesis of 2S-((E)-2-ethoxy-5-propenyl-phenoxy)-1-(3,4,5-trimethoxy-phenyl)-propane-1-one.
2. Artificial vanilla flavoring, flavor enhancer.
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.

Check Digit Verification of cas no
The CAS Registry Mumber 94-86-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 94-86:
(4*9)+(3*4)+(2*8)+(1*6)=70
70 % 10 = 0
So 94-86-0 is a valid CAS Registry Number.

Selective dealkylations of alkyl aryl ethers in heterogeneous basic media under microwave irradiation
Oussaid, Abdelouahad,Thach, Le Ngoc,Loupy, Andre
, p. 2451 - 2454 (2007/10/03)
Ethyl isoeugenol and 2-ethoxyanisole could be selectively deethylated using potassium t-butoxide in the presence of crown ether under solvent-free conditions. By addition of ethylene glycol, selectivity was reversed to demethylation. In both cases, strong enhancements were observed under focused microwaves.
