Chlorine-oxygen chemistry studies compounds that combine chlorine and oxygen. The best known species include chlorine monoxide (ClO), chlorine dioxide (ClO2), dichlorine monoxide (Cl2O), and dichlorine heptoxide (Cl2O7). These oxides vary in stability and reactivity and appear in contexts from the atmosphere to laboratory and industrial settings.

Chlorine monoxide (ClO) is a reactive radical formed in the atmosphere when chlorine reacts with ozone and oxygen species. In stratospheric chemistry, ClO participates in catalytic cycles that contribute to ozone depletion, especially under the influence of sunlight and other halogens.

Chlorine dioxide (ClO2) is an odd-electron oxidant used commercially for bleaching and disinfection. It is typically generated in situ and stored as a solution or stabilized gas because it is unstable and can be hazardous. Its strong oxidizing power makes it effective in certain industrial processes, but also requires careful handling to prevent runaway reactions.

Dichlorine monoxide (Cl2O) is a molecular oxide observed under specialized conditions, while dichlorine heptoxide (Cl2O7) is a powerful oxidizer and the anhydride of chloric acid (HClO3). Both are highly reactive and require careful handling due to corrosion, toxicity, and potential explosive hazards.

In environmental contexts, chlorine-oxygen chemistry contributes to oxidative processes and pollutant transformations in the atmosphere. Industrial applications include bleaching, water treatment, and chemical synthesis, but safety concerns and regulatory controls govern the use and handling of these compounds.
