DMSO is a polar aprotic solvent and is less toxic than other members of this class, such as dimethylformamide, dimethylacetamide, N-methyl-2-pyrrolidone, and HMPA. DMSO is frequently used as a solvent for chemical reactions involving salts, most notably Finkelstein reactions and other nucleophilic substitutions.
Industrial-grade DMSO is not of the same quality as the DMSO that is used for drug research purposes since it may contain impurities. DMSO easily penetrates the skin and brings along impurities and other substances that may be hazardous to health.
