The Properties, Specifications, Monograph and Uses of Dimethyl Sulfoxide or DMSO:
Dimethyl Sulfoxide or DMSO is a highly versatile, polar aprotic solvent widely used for its exceptional ability to dissolve both polar and non-polar chemical compounds. DMSO serves as a vehicle or carrier in topical ointments and creams. It rapidly crosses the skin barrier, dragging active pharmaceutical ingredients along with it for faster localized absorption. DMSO is uses as a safe, highly stable chemical medium for major industrial reactions involving salts, such as Finkelstein reactions, nucleophilic substitutions, and peptide synthesis.
Specifications of Dimethyl Sulfoxide DMSO USP Grade:
C2H6OS -- 78.13
Methane, sulfinylbis-.
Methyl sulfoxide --- CAS 67-68-5.
Dimethyl Sulfoxide contains not less than 99.9 percent of C2H6OS, calculated on the anhydrous basis.
Packaging and storage: Preserve in tight, light-resistant containers.
Identification:
A: Infrared Absorption.
B: Add 1.5 mL cautiously and dropwise to 2.5 mL of hydriodic acid in a test tube cooled in ice. Filter the mixture rapidly and collect the precipitate. Dry the precipitate in vacuum: a deep violet, crystalline solid is obtained, and it is soluble in chloroform, yielding a red solution.
Specific gravity: between 1.095 and 1.101.
Refractive index: between 1.4755 and 1.4775.
Acidity: Dissolve 50.0 g in 100 mL of water and add phenolphthalein. If the solution remains colorless, titrate with 0.01 N sodium hydroxide until a pink color appears: not more than 5.0 mL of 0.01 N sodium hydroxide is consumed.
Water Determination: not more than 0.1%. [ note— Weigh and transfer the test specimen in an environment of low humidity to minimize absorption of atmospheric water.]
Ultraviolet absorbance: Maintain Dimethyl Sulfoxide in a water bath at a temperature of less than 20C [note— Do not freeze.], and purge with dry nitrogen for 30 minutes. Record the UV absorption spectrum between 270 and 350 nm in a 1-cm cell, using water as the blank: the spectrum is smooth with no absorption maxima; the absorbance at 275 nm is not more than 0.20, and the absorbance ratios, A 285 / A 275 and A 295 / A 275, at the wavelengths indicated by the subscripts, are not more than 0.65 and 0.45, respectively.
Limit of nonvolatile residue: Evaporate about 100.0 g to dryness in a tared, preconditioned dish on a hot plate under a suitable fume hood. Evaporate gently so boiling does not occur. The weight of the residue does not exceed 0.01%.
Related compounds: To pass the test by chromatography --- not more than 0.1% of total impurities is found.
Assay: Using the results from the test for Limit of nonvolatile residue and the test for Related compounds, calculate the percentage of C2H6OS in the portion of Dimethyl Sulfoxide taken by subtracting the percentage of nonvolatile residue and the percentage of total impurities found from 100.0%. [note— A correction for percent water is not applied to the result.]
