Ethylurea Usage And Synthesis
Chemical Propertieswhite to beige crystals
UsesN-Ethylurea, is a versatile building block, that can be used in organic synthesis of various pharmaceutical and biologically active compounds, as Nitrogen and Carbonyl source.
Safety ProfileMddly toxic by parenteral route. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
Purification MethodsCrystallise the urea from EtOH/water, then dry it under vacuum at room temperature. [Beilstein 4 IV 369.]
