描述：

Dimethyl Sulfoxide

ACS Reagent Grade
Purity: ≥99.9
Specific gravity: 1.10 gm/ml
clear, colorless liquid.
Synonyms: Methyl Sulfoxide: DMSO

Structure:

Molecular Formula: C₂H₆SO (for non-heavy labels)

Molecular Weight: 78.13 (non-heavy labels)

CAS #: 67-68-5

Synonyms: DMSO; Methyl sulfoxide; Methyl sulphoxide; Sulfinylbismethane

Physical Description: Clear colorless liquid to solid. The melting point is approximately 18°C so the product may appear anywhere from the liquid phase to the solid phase when in the pure form. By heating the solid form to approximately 30°C, the product can be melted without harming it's stability. DMSO supercools easily; melts at room temperature slowly.

Solubility: Soluble in water, methanol, acetone, ether, benzene, chloroform.¹ To prepare sterile solutions use a a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.

Stability: A thermally stable compound. DMSO is stable up to 100°C in alkaline, acidic and neutral conditions. It is stable in neutral or alkaline conditions at temperatures approaching its boiling point of 189°C. DMSO can be heated to 150°C for 24 hours with less than 0.1% loss in purity.⁵

DMSO is very hygroscopic.¹

Density: Approximately 1.10 g/ml

Autoprotolysis constant: Approximately 33 at 25°C.⁷

Dielectric constant: 45 ¹

Description: A dipolar, aprotic solvent.¹ Has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination.^3,8

Typical Uses:

- Used to enhance dermal absorption of many chemicals.
- A solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers.
- Used in antifreeze or hydraulic fluids.
- As a cryopreservative for cell cultures.⁵
- Used in the oxidation of thiols and disulfides to sulfonic acids.⁴
- Used as a PCR cosolvent to help improve yields, especially in long PCR.
