General description

Hydrogen peroxide solution is commonly used as a bleaching agent. It shows germicidal and sporicidal properties. H2O2 is a reactive oxygen species formed as a reaction product of various aerobic metabolic processes. Its ultra-trace quantification in the concentration range of 10-11mole/ml by a fluorometric method has been described.


Greener oxidant used for bromination of 1,3-dicarbonyl compounds, amide bond formation from amines and aldehydes, halogenation of aromatic compounds and dethioacetalization.

Highly Selective Oxidative Monochlorination To Synthesize Organic Intermediates: 2-Chlorotoluene, 2-Chloroaniline, 2-Chlorophenol, and 2-Chloro-4-methylphenol

Hydrogen peroxide solution has also been used in the preparation of ′Piranha′, a sulfuric acid/hydrogen peroxide mixture for cleaning silicon wafers used in nanostructure-initiator mass spectrometry (NIMS) chips.
It can be used as an oxidant for:
• Epoxidation of terminal olefins under halide-free conditions.
• Oxidation of cyclohexene to adipic acid under organic solvent- and halide-free conditions.

Hydrogen peroxide solution has been used in an immunoblotting protocol.
