Hydrogen Peroxide

General Information:


CAS Number: 7722-84-1

Molecular Weight: 34.01 g/mol

Appearance: Colorless liquid

Density: 1.11 g/mL (30% w/w aq.)

Hydrogen peroxide is the simplest peroxide and is considered a strong oxidizer. It exists as a colorless liquid and is miscible with H2O in all proportions. For laboratory purposes 30% Hydrogen peroxide (in H2O) is most common.

Common Uses:

Reagent for the oxidation of sulfides to sulfoxides or sulfones

Reagent for the conversion of nitriles to amides

Reagent in the second step of the conversion or an aryl halide to an aryl-OH
