N,N'-DIMETHYLTHIOUREA Usage And Synthesis
DescriptionDimethylthiocarbamide, an antioxygen agent, is responsible for sensitization, when unexposed to light, from diazo papers.
Chemical Propertiescolorless to white crystals, crystalline powder
UsesN,N'-Dimethylthiourea is an antioxidant present in diazo copy paper to prevent yellow discoloration of the paper.
UsesIntermediate in the preparation of Arginine derivatives.
Contact allergensDimethylthiocarbamide, an antioxygen agent, is responsible for sensitization, when unexposed to light from diazo papers.
Safety ProfileModerately toxic by ingestion. Experimental teratogenic and reproductive effects. When heated to decomposition it emits toxic fumes of SOx andNO,.
