1-Methyl-1-nitrosourea Usage And Synthesis |
Chemical Properties | Off-White to Pale Yellow Solid |
Usage | Precursor of Diazomethane. It has a cytotoxicity effect. This product contains an undetermined amount of water |
General Description | Pale yellow crystals or light yellow moist powder. |
Air & Water Reactions | Sensitive to humidity and light when pure. Insoluble in water. Slowly decomposes in water. Alkaline hydrolysis produces a highly toxic, irritating and explosive gas. |
Reactivity Profile | 1-Methyl-1-nitrosourea is incompatible with strong acids and bases. Also incompatible with water and nucleophilic reagents. Alkaline hydrolysis produces a highly toxic, irritating and explosive gas. Can detonate with (potassium hydroxide + methylene chloride) . |
Fire Hazard | Flash point data for 1-Methyl-1-nitrosourea are not available; however, 1-Methyl-1-nitrosourea is probably combustible. |
