Specification
Monothioglycerol (96-27-5) also can be called 1,2-Dihydroxy-3-mercaptopropane ; 1-Thio-DL-glycerol ; 3-Sulfanyl-1,2-propanediol ; a-Monothioglycerol ; .alpha.-Monothioglycerol ; 1,2-propanediol, 3-mercapto- ; .alpha.-Thiolglycerol ; 3-Sulfanyl-1,2-propandiol ; 3-Sulfanylpropane-1,2-diol .It is hazardous,so the first aid measures and others should be known.Such as: When on the skin: should flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing. Or in the eyes: 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 victim is conscious and alert, give 2-4 cupfuls of milk or water.
In addition, Monothioglycerol (96-27-5) can be stable under normal temperature and pressure conditions.It is not compatible with strong oxidants, reducing agents, bases, alkali metals,and you must not take it with strong oxidants and incompatible materials.And also prevent it to broken down into hazardous decomposition products: irritating and toxic fumes and gases, hydrogen sulfide, carbon dioxide, carbon monoxide, oxides of sulfur.
