Sulfoxide is a chemical compound that contains a sulfur atom bonded to an oxygen atom and two carbon atoms. It is commonly represented by the formula R2SO, where R represents organic groups. One of the most well-known examples of sulfoxide is dimethyl sulfoxide (DMSO), which is used as a solvent in various chemical reactions and has applications in pharmaceuticals. Sulfoxides are characterized by their polar nature, which allows them to dissolve both polar and nonpolar substances. They are often used in organic synthesis and can act as intermediates in the production of other chemicals. Additionally, sulfoxides have unique properties that make them useful in biological research and drug development.
