The material has the unusual property of changing to ammonium thiocyanate upon heating above 130 °C. Upon cooling, the ammonium salt converts back to thiourea. Thiourea reduces peroxides to the corresponding diols. The intermediate of the reaction is an unstable endoperoxide. WebWhat is the percentage by mass of carbon in CS (NH2)2?
