| 4-Methyl-5-thiazolylethyl acetate Usage And Synthesis |
| Description | May be prepared from 2-methylthio-4-methyl-5-(2-acetoxyethyl)- thiazole and AlHg; by dehydrogenation with sulfur at 130°C of the (i-acetyl derivative of 4-methyl-5-(P-hydroxyethyl)-3-thiazoline. |
| Chemical Properties | Colorless to light yellow liqui |
| Chemical Properties | 4-Methyl-5-thiazoleethanol acetate has an odor reminiscent of meat. |
| Uses | 4-Methyl-5-thiazolylethyl Acetate is used in biological study for research on contribution of oxidized tallow to aroma characteristics of beeflike process flavor assessed by gas chromatography-mass spectrometry and partial least squares regression. |
| Preparation | From 2-methylthio-4-methyl-5-(2-acetohxyethyl)-thiazole and AlHg; by dehydrogenation with sulfur at 130°C of the β-acetyl derivative of 4-methyl-5-(β-hydroxyethyl)-3-thiazoline |
| Definition | ChEBI: 5-(2-Hydroxyethyl)-4-methylthiazole acetate is a member of thiazoles. |
| Taste threshold values | Taste characteristics at 10 ppm: meaty, brothy, bready and brown with a beefy, bloody and chicken note. |
