Hydrogen peroxide is a chemical compound with the formula H. 2O. 2. In its pure form, it is a colourless liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide (a compound with an oxygenâoxygen single bond). It is used as an oxidizer, bleaching agent and disinfectant. Concentrated hydrogen peroxide, or high-test peroxide, is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.
