    Brief Overview

    Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3 ) 2 SO. It is a
    colorless liquid and is an important polar aprotic solvent that is able to dissolve both polar
    and non-polar compounds and is miscible in a variety of organic solvents as well as water.
    DMSO has the unusual property that many individuals perceive a garlic-like taste in the
    mouth after contact with the skin.
    In terms of chemical structure, the molecule has idealized C s  symmetry. It has a trigonal
    pyramidal molecular geometry consistent with other three-coordinate S(IV)
    compounds, with a non bonded electron pair on the approximately tetrahedral sulfur atom.

    Manufacturing Process
    DMSO was first synthesized in 1866 by the Russian scientist Alexander Zaytsev, who
    reported his findings in 1867. Dimethyl sulfoxide is produced industrially from dimethyl
    sulfide, a by-product of the Kraft process, by oxidation with oxygen or nitrogen dioxide.

    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. It is also extensively used as an extractant in
    biochemistry and cell biology.

    Use of DMSO in medicine dates from around 1963, when an Oregon Health & Science
    University Medical School team, headed by Stanley Jacob, discovered it could penetrate the

    skin and other membranes without damaging them and could carry other compounds into a
    biological system. In 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. Its effect may be enhanced with the addition of EDTA. It is frequently
    compounded with antifungal medications, enabling them to penetrate not just skin but also
    toenails and fingernails.
