Description

General description

Urea hydrogen peroxide (UHP) is an oxidizing agent consisting of urea and hydrogen peroxide. In the presence of carboxylic anhydrides, UHP is employed in a variety of oxidative conversions in anhydrous organic solvents. UHP is used as a hydrogen peroxide source in the oxidation reaction.

Application

Urea hydrogen peroxide can be used as an oxidizing agent:

• In the conversion of sulfides to sulfoxides or sulfones under solvent free condition.
• In the conversion of nitrogen heterocycles to their corresponding N-oxides.
• In the epoxidation of various alkene in combination with number of carboxylic anhydrides and disodium hydrogen phosphate in anhydrous organic solvents.
• In the Baeyer–Villiger oxidation reaction where in aldehydes and ketones undergo oxidation to produce esters and lactones using various peroxycarboxylic acids.

Features and Benefits

UHP is:

• Inexpensive.
• Stable.
• Easy handling reagent.
