Uses

Used in Flavor and Fragrance Industry:
Propenyl Guaethol is used as an artificial vanilla flavoring and flavor enhancer due to its strong vanilla-like taste and odor. It has a taste threshold value of 25 ppm and an aroma threshold value of 400 ppb, with aroma characteristics at 1.0% being vanilla, sweet, spicy, slightly phenolic, and having a heliotropine-like creaminess.
Used in Chemical Synthesis:
Propenyl Guaethol is also used in the synthesis of other chemical compounds, such as 2S-((E)-2-ethoxy-5-propenyl-phenoxy)-1-(3,4,5-trimethoxy-phenyl)-propane-1-one.

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.

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.
