    Chemical Name: Dimethyl Sulfoxide (DMSO)

    Synonyms Dimethyl sulfoxide; Methyl sulfoxide; Sulfinylbismethane; Methylsulfinylmethane

    CAS N o: 67-68-5

     

    Priary Use DMSO is made by oxidation of dimethyl sulfide (e.g., with nitrogen dioxide or hydrogen peroxide). Industrially used in: pharma (synthesis medium, transdermal penetration enhancer), electronics (photoresist stripper, semiconductor cleaning, Li-battery electrolyte co-solvent), fibers (PAN carbon-fiber spinning, acrylic/acetate solvents), aromatic & butadiene extraction, agrochemical solvent/additive, paint stripper, and cryoprotectant for cells/tissues. Low toxicity but can induce skin sensitization
