Chemical PropertiesCLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID
Chemical Properties4-Methylthiazole has a nutty, green odo
OccurrenceReported found in cooked asparagus, roasted barley, cooked beef, cocoa, cooked pork, roasted coffee, roasted peanuts, boiled egg, malt, wort and cooked shrimp.
Uses4-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.
DefinitionChEBI: A 1,3-thiazole substituted by a methyl group at position 4.
Taste threshold valuesTaste characteristics at 10 ppm: green, vegetative and meaty with an alliaceous nuance
General Description4-Methylthiazole forms complexes with cobalt(II), zinc(II), nickel(II) and copper(II) halides.
