Description and Uses

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.

5-(2-Hydroxyethyl)-4-methylthiazole has been used in the synthesis of novel thiazolium halogenide ionic liquids.
