Bahan kimia |
Katon tanpa cairan kanggo cairan berminyak kenthel kuning. Werna bakal peteng sawise dadi panyimpenan jangka panjang. Iki ngasilake ambu senyawa thiophene sing ora enak kanthi aroma kacang kanggo encer sing dhuwur. Titik sing nggodhok yaiku 103 ° C (133 Pa), utawa 135 ° C (933 Pa). Gampang larut ing banyu, larut ing etanol, eter, benzena lan kloroform. |
|
Preparasi |
Iki dipikolehi saka nyuda pangurangan 4-metil thiazole 5-etil asetat kanthi hidrida lithium aluminium. |
|
Katrangan |
4-Methy 1-5-thiazoleethanol duweni ciri ambu senyawa thiazole sing ora bisa ditampa. Rasane nyenengake lan kaya kacang nalika diencerke banget. Bisa uga disiapake kanthi nyuda etil- 4-methylthiazole-5-acetate nggunakake LiAlH4; kanthi kondensasi tioformamide karo bromoacetopropanol utawa karo y, y-dichloro-y, ydiacetodipropyl eter. |
|
Properti Kimia |
4-Methyl-5-thiazoleethanol duwé ambu ora enak sing khas ing senyawa thiazole; rada nyenengake, ngelingake daging sapi lan kacang-kacangan, nalika diencerke banget |
|
Properti Kimia |
Liqui kuning sing ora ana warna lan entheng |
|
