·      DMSO is frequently used as a solvent for chemical reactions involving salts, most notably Finkelstein reactions and other nucleophile substitutions.

·      It is also extensively used as an extract ant in biochemistry and cell biology.

·      DMSO is used in polymerase chain reaction (PCR) to inhibit secondary structures in the DNA template or the DNA primers.

·      DMSO may also be used as a cry protectant, added to cell media to reduce ice formation and thereby prevent cell death during the freezing process.

·      medicine, DMSO is predominantly used as a topical analgesic, a vehicle for topical application  of pharmaceuticals, as an anti-inflammatory, and an antioxidant.[19] Because DMSO increases the rate of absorption of some compounds through biological tissues, including skin, it is used in some transdermal drug delivery systems.
