Thion

Thion is a chemical compound with the formula S2O3. It is a colorless, crystalline solid that is soluble in water. Thion is primarily used as a reducing agent in various chemical processes. It is also known for its ability to form complexes with metals, which is useful in analytical chemistry and in the production of certain dyes and pigments. Thion is typically prepared by the reaction of sulfur with an oxidizing agent, such as hydrogen peroxide or potassium permanganate. It is important to handle thion with care due to its potential to cause skin and eye irritation. Thion is not classified as a hazardous substance under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), but it is still recommended to use appropriate personal protective equipment when handling it. Thion is a versatile compound with applications in both industrial and laboratory settings.
