5-(2-Hydroxyethyl)-4-methylthiazole（bean）Usage And Synthesis
Content analysis | It was determined by gas chromatography (GT-10-4) using a nonpolar column method. |
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. |
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. |
