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

4-Methyl-5-thiazoleethanol is a sulfur-containing heterocyclic flavor compound that is reported to occur in Comté cheese and Panax ginseng.
