Oxamide is a white crystalline solid, which is soluble in ethanol, slightly soluble in water and insoluble in diethyl ether. Heating it in air to temperatures above 350°C causes decomposition yielding cyanogen and water. Oxamide is the double amide of oxalic acid.
[edit] Applications
It is used as a stabilizer for nitrocellulose preparations and may substitute urea in fertilizers.
Oxamide has proved a useful research tool due its ability to form self-assembled monolayers consisting of a hydrogen bonded network.[1]
