Hydrogen Peroxide-Urea

[124-43-6] CH6N2O3 (MW 94.09) InChI = 1S/CH4N2O.H2O2/c2-1(3)4;1-2/h(H4,2,3,4);1-2H InChIKey = AQLJVWUFPCUVLO-UHFFFAOYSA-N (alternative to 90% hydrogen peroxide as a source of anhydrous hydrogen peroxide for use in oxidation reactions) Alternate Name: UHP. Physical Data: mp 84–86 °C (dec).2 Solubility: sol water and alcohols; low solubility in organic solvents such as dichloromethane. Form Supplied in: white crystalline powder with urea as impurity; commercially available. Drying: over calcium chloride in a desiccator. Preparative Method: made by the recrystallization of Urea from aqueous Hydrogen Peroxide Handling, Storage, and Precautions: the pure material should be stored at low temperature but the commericial material, which has a purity of ca. 90%, may be stored at rt. In a sufficiently forcing test, it can be made to explode; its decomposition is acceleratory above 82 °C. Conduct work with this reagent in an efficient fume hood behind a polycarbonate safety screen.
