| 5-(2-Hydroxyethyl)-4-methylthiazole Usage And Synthesis |
| Content analysis | It was determined by gas chromatography (GT-10-4) using a nonpolar column method. |
| Toxicity | GRAS (FEMA) |
| Usage limit FEMA | soft drinks, cold drinks, candy, baked goods, jelly, pudding, jelly sugar, seasonings, meat products, meat soup, milk and dairy products as well as cereal product: 55.0mg/kg. |
| Chemical properties | It appears as colorless to pale yellow viscous oily liquid. The color will turn dark after being subject to long-term storage. It emit unpleasant thiophene compound odor with high dilution generating nut aroma. The boiling point is 103 ° C (133 Pa), or 135 ° C (933 Pa). It is easily soluble in water, soluble in ethanol, ether, benzene and chloroform. |
| Application |
|
| Preparation | It is obtained from the reduction of 4-methyl thiazole 5-ethyl acetate reduction with lithium aluminum hydride. |
| Description | 4-Methy 1-5-thiazoleethanol has the characteristic disagreeable odor of thiazole compounds. It is somewhat pleasant and nut-like on extreme dilution. It may be prepared by reduction of ethyl- 4-methylthiazole-5-acetate using LiAlH4; by condensation of thioformamide with bromoacetopropanol or with y,y-dichloro-y,ydiacetodipropyl ether. |
| Chemical Properties | 4-Methyl-5-thiazoleethanol has a disagreeable odor typical of thiazole compounds; somewhat pleasant, reminiscent of beef and nut-like, on extreme dilution |
| Chemical Properties | Colorless to light yellow liqui |
| Occurrence | Reported found in grilled and roasted beef, cognac, brandy, Finnish whiskey, cocoa, peanuts, beans and malt. |
| Preparation | By reduction of ethyl-4-methylthiazole-5-acetate using LiAlH4; by condensation of thioformamide with bromoacetopropanol or with γ, y-dichloro-γ,γ-diacetodipropyl ether |
