Ethylurea Usage And Synthesis

Chemical Properties

white to beige crystals

Uses

N-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 Profile

Mddly toxic by parenteral route. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise the urea from EtOH/water, then dry it under vacuum at room temperature. [Beilstein 4 IV 369.]
