Peroxides are a group of compounds with the structure R−O−O−R, where R = any element.[1][2] The O−O group in a peroxide is called the peroxide group or peroxo group. The nomenclature is somewhat variable.[3]

The most common peroxide is hydrogen peroxide (H2O2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well.
