4,5-Dimethylthiazole Chemical Properties,Uses,Production

Chemical Properties

4,5-Dimethylthiazole is a colorless to light yellow liquid that has a roasted nutty, meaty, boiled poultry-like odor.

Occurrence

Reported found in peanuts, toasted oats, malt, peach, pork, coffee, krill, shrimp and scallops

Uses

4,5-Dimethylthiazole was used in the preparation of 4-(bromomethyl)-5-(dibromomethyl)thiazole.

Preparation

From methyl-α-bromoethyl ketone; by oxidation of 2-mercaptothiazoles with hydrogen peroxide in aqueous solution; from 2-mercapto-4,5-dimethylthiazole.

General Description

4,5-Dimethylthiazole is a thiazoles compounds that containing a thiazole ring substituted at positions 4 and 5 only. Radical bromination of 4,5-dimethylthiazole using N-bromosuccinimide in the presence of 2,2′-azobisisobutyronitrile yields mono-, tri- and tetrabromo compounds.
