General description

Dimethyl sulfoxide (DMSO) is an organosulfur compound which is a dipolar aprotic solvent. It remains liquid across a broad temperature range, acts as a strong electron donor, and possesses high polarity. These characteristics make it an excellent and selective solvent for a variety of organic and even polymeric compounds. DMSO is a widely used solvent in organic synthesis and analytical applications since it is fully miscible with water and various organic solvents, enabling it to dissolve both polar and nonpolar substances.
