Dimethyl Sulfoxide or DMSO or Methylsulfinylmethane or Methyl Sulfoxide SDS of Manufacturers

DMSO or Dimethyl Sulfoxide Manufacturers

Synonyms: Dimethyl Sulfoxide or DMSO or Methylsulfinylmethane or Methyl Sulfoxide
CAS Number: 67-68-5, Molecular Weight: 78.13, Chemical Formula: C2H6OS or (CH3)2SO, EINECS EC Number: 200-664-3, FEMA: ----,

Dimethyl sulfoxide or DMSO or Methylsulfinylmethane or Methyl sulfoxide is an organosulfur compound with the formula (CH3)2SO. This colorless liquid is used as a polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. DMSO is predominantly used as a topical analgesic, a vehicle for topical application of pharmaceuticals, as an anti-inflammatory, and an antioxidant. Dimethyl Sulfoxide is commonly used in veterinary medicine as a liniment for horses, alone or in combination with other ingredients.

General Properties and Specifications of Dimethyl Sulfoxide or DMSO or Methylsulfinylmethane or Methyl sulfoxide:
Appearance: Colorless.
Assay: 99.8% minimum.
Odor: Almost odorless or say Slightly sulfurous odor.
Acid Value: 0.03 maximum.
Moisture: 0.10 maximum.
Relative density: 1.1
Melting point: 17C to 19C.
Boiling point: 189C.
Flash point: 87C minimum reported.
Auto-ignition temperature: 300C.
Solubility: Miscible with water. Soluble in ethanol, acetone, ether, carbon tetrachloride, ethyl acetate.

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.
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.]

Specifications of Dimethyl Sulfoxide BP Ph Eur Grade:

Action and use: Pharmaceutical solvent; excipient.
When dimethyl sulphoxide is demanded, Dimethyl Sulfoxide shall be supplied.


Appearance: Colourless liquid or colourless crystals, hygroscopic.
Solubility: Miscible with water and with ethanol (96 per cent).

First identification: C
Second identification: A, B, D
A. Relative density.
B. Refractive index.
C. Infrared absorption spectrophotometry.
Comparison dimethyl sulfoxide CRS.
D. Dissolve 50 mg of nickel chloride in 5 mL of the substance to be examined. The solution is greenish-yellow. Heat in a water-bath at 50 °C. The colour changes to green or bluish-green. Cool. The colour changes to greenish-yellow.

Acidity: Dissolve 50.0 g in 100 mL of carbon dioxide-free water. Add 0.1 mL of phenolphthalein solution. Not more than 5.0 mL of 0.01 M sodium hydroxide is required to produce a pink colour.
Relative density: 1.100 to 1.104.
Refractive index: 1.478 to 1.480.
Freezing point: Minimum 18.3C.
Absorbance: Purge with nitrogen for 15 min. The absorbance, measured using water as the compensation liquid, is not more than 0.30 at 275 nm and not more than 0.20 at both 285 nm and 295 nm. Examined between 270 nm and 350 nm, the substance to be examined shows no absorption maximum.
Related substances: To pass the test by Gas chromatography.
Water: Maximum 0.2 per cent, determined on 10.0 g.

In an airtight, glass container, protected from light.
