What is Hydrogen thioperoxide?

Hydrogen thioperoxide, also called oxadisulfane or sulfur hydride hydroxide, is the chemical with the structure H–S–O–H. It can be considered as the simple sulfur-substituted analog of the common hydrogen peroxide chemical, and as the simplest hydrogen chalcogenide containing more than one type of chalcogen. The chemical has been described as the "missing link" between hydrogen peroxide and hydrogen disulfide , though it is substantially less stable than either of the other two. It is the inorganic parent structure of the sulfenic acid class of organic compounds and also the oxadisulfide linkage , where "R" is any organic structure. Sulfur is present in oxidation state 0.
