Trioxidane

Trioxidane, also called dihydrogen trioxide, is the chemical compound with the formula H₂O₃. It is the simplest polyoxide, a type of chemical that has three or more oxygen atoms linked together in a chain. This family of chemicals is related to water and hydrogen peroxide, but they are much more unstable.

Trioxidane is a proposed reaction intermediate for when living things make ozone from singlet oxygen, but this is debated because H₂O₃ breaks apart into water and oxygen, not ozone and hydrogen peroxide.
