4-Methyl-5-thiazoleethanol Specification
4-Methyl-5-thiazoleethanol , its cas register number is 137-00-8. It also can be called Sulfurol ; 4-Methyl-5-(2'-hydroxyethyl)-thiazole ; 5-(2-Hydroxyethyl)-4-methylthiazole ; 4-Methyl-5-beta-hydroxyethyl thiazole ; and 4-Methyl-5-hydroxyethylthiazole . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Or in the eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. While, it's inhaled: Remove from exposure and move to fresh air immediately. Then you have the ingesting of the product: Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
In addition, 4-Methyl-5-thiazoleethanol (CAS NO.137-00-8) could be stable under normal temperatures and pressures. It is not compatible with strong oxidizing agents, and you must not take it with incompatible materials. And also prevent it to broken down into hazardous decomposition products: Nitrogen oxides, carbon monoxide, oxides of sulfur, irritating and toxic fumes and gases, carbon dioxide, nitrogen.
