Application
- Used as temporarily allowable food spices;
- For nuts, dairy products, meat products, etc., as pharmaceutical intermediates;
- Used for the deployment of chocolate, milk and nuts
Preparation
It is obtained from the reduction of 4-methyl thiazole 5-ethyl acetate reduction with lithium aluminum hydride.
Description
4-Methy 1-5-thiazoleethanol has the characteristic disagreeable odor of thiazole compounds. It is somewhat pleasant and nut-like on extreme dilution. It may be prepared by reduction of ethyl- 4-methylthiazole-5-acetate using LiAlH4; by condensation of thioformamide with bromoacetopropanol or with y,y-dichloro-y,ydiacetodipropyl ether.
Chemical Properties
4-Methyl-5-thiazoleethanol has a disagreeable odor typical of thiazole compounds; somewhat pleasant, reminiscent of beef and nut-like, on extreme dilution
Chemical Properties
Colorless to light yellow liqui
Occurrence
Reported found in grilled and roasted beef, cognac, brandy, Finnish whiskey, cocoa, peanuts, beans and malt.
Uses
4-Methyl-5-thiazoleethanol has been used in the synthesis of novel thiazolium halogenide ionic liquids.
Preparation
By reduction of ethyl-4-methylthiazole-5-acetate using LiAlH4; by condensation of thioformamide with bromoacetopropanol or with γ, y-dichloro-γ,γ-diacetodipropyl ether
Definition
ChEBI: A 1,3-thiazole that is thiazole substituted by a methyl group at position 4 and a 2-hydroxyethyl group at position 5.
Taste threshold values
Taste characteristics at 20 ppm: meaty, brothy, roasted, metallic and nutty.
General Description
