Application A relatively stable source of hydrogen peroxide for preparation of solutions. Other Notes An addition compound of urea and hydrogen peroxide.
Quantity One tablet will provide the equivalent of 1.75 mg of H2O2. Reconstitution When dissolved in 12.5 mL deionized water, one tablet yields a solution containing 0.014% H2O2. Specificity Urea Hydrogen Peroxide Tablets provide a safe and convenient source of H2O2 for use in enzyme immunoassay and other procedures.
Application Peroxide used with N-halosuccinimides in an efficient α-halogentation of carbonyl compounds.1 Used with methyltrioxorhenium (412910) in a mild oxidation of imines to nitrones.2 Also used to oxidize iodoarenes to hypervalent iodine compounds.3 Packaging 100, 250 g in poly bottle 5 g in glass bottle
A mixture obtained by combining equimolar amounts of hydrogen peroxide and urea.
