Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound. It is a colorless and odorless transparent liquid at room temperature, and is a hygroscopic flammable liquid. It has the characteristics of high polarity, high boiling point, good thermal stability, non proton, and miscibility with water. It is soluble in most organic compounds such as ethanol, propanol, benzene, and chloroform, and is known as the "universal solvent". In the presence of acid, heating will produce a small amount of Methanethiol, formaldehyde, dimethyl sulfur, methanesulfonic acid and other compounds. Under high temperatures, there is decomposition phenomenon, which can react violently with chlorine and emit a light blue flame when burned in the air. It can be used as an organic solvent, reaction medium, and intermediate in organic synthesis. It can also be used as dyeing solvent, dye remover, dyeing carrier of Synthetic fiber, and absorbent for recovering acetylene and sulfur dioxide.
