Chemical Properties

4-Methylthiazole has a nutty, green odo

Chemical Properties

CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID

Occurrence

Reported found in cooked asparagus, roasted barley, cooked beef, cocoa, cooked pork, roasted coffee, roasted peanuts, boiled egg, malt, wort and cooked shrimp.

Uses

4-Methylthiazole was used in the synthesis of catalytic dendrophanes, as functional mimics of the thiamine-diphosphate-dependent enzyme pyruvate oxidase. It was used in small scale preparation of 3-butyl-4-methylthiazolium bromide.

Definition

ChEBI: A 1,3-thiazole substituted by a methyl group at position 4.

Taste threshold values

Taste characteristics at 10 ppm: green, vegetative and meaty with an alliaceous nuance

General Description

4-Methylthiazole forms complexes with cobalt(II), zinc(II), nickel(II) and copper(II) halides.
