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.
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
