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. |
