Description:

  • Chemical Formula: (CH3)2SO
  • Molecular Weight: Approximately 78.13 g/mol
  • Structure: Dimethyl Sulfoxide is an organic compound with a sulfoxide functional group (-SO). It is a colorless liquid with a characteristic odor.

Specification:

  • Purity: Dimethyl Sulfoxide is commercially available in various purity grades, typically ranging from 99% to higher levels. The specific purity may depend on the intended application and the manufacturer.
  • Solubility: Dimethyl Sulfoxide is highly miscible with water and other organic solvents, making it an excellent solvent for a wide range of substances.

Application:

  1. Industrial Solvent: Dimethyl Sulfoxide is widely used as a solvent in various industrial applications. It has excellent solvency power and can dissolve a wide range of polar and non-polar compounds. It is commonly used in chemical reactions, pharmaceutical synthesis, polymer processing, and as a reaction medium in certain industrial processes.

  2. Pharmaceutical Industry: Dimethyl Sulfoxide is utilized in the pharmaceutical industry for its ability to enhance drug delivery and solubility. It can act as a vehicle or co-solvent in formulations to improve the absorption and bioavailability of certain drugs. It is also used in the development and testing of pharmaceutical compounds.

  3. Veterinary and Medical Applications: Dimethyl Sulfoxide has been used in veterinary and medical practices for its potential anti-inflammatory and analgesic properties. It can be applied topically or used as a carrier for drug delivery in certain veterinary and medical treatments.

  4. Cryoprotectant: Dimethyl Sulfoxide has cryoprotective properties, meaning it can protect cells and tissues from damage during freezing and thawing processes. It is commonly used as a cryoprotectant in cell and tissue preservation, including the cryopreservation of stem cells and certain biological samples.

Features:

  • Excellent Solvent Properties: Dimethyl Sulfoxide is known for its high solvency power, enabling it to dissolve a wide range of substances, both polar and non-polar.

  • Penetration Enhancer: Dimethyl Sulfoxide has the ability to enhance the permeability of biological membranes, making it useful as a penetration enhancer in certain drug formulations.

  • Cryoprotective Agent: Dimethyl Sulfoxide exhibits cryoprotective properties, allowing for the preservation of cells and tissues during freezing and thawing processes.

  • Low Toxicity: Dimethyl Sulfoxide is generally considered to have low toxicity. However, it can readily penetrate the skin, so handling and exposure should be done with appropriate precautions.

  • Hygroscopic Nature: Dimethyl Sulfoxide has hygroscopic properties, meaning it readily absorbs moisture from the air. Proper storage and handling are necessary to prevent contamination and maintain its quality.

Uses

Dimethyl sulfoxide (CAS NO. 67-68-5) is an important polar aprotic solvent. It is widely used to strip photoresist in TFT-LCD 'flat panel' displays and advanced packaging applications (such as wafer-level packaging / solder bump patterning). It also used in biopresevation especially stem cell banking. It is predominantly used as a topical analgesic, a vehicle for topical application of pharmaceuticals, as an anti-inflammatory, and an antioxidant.

Production

Dimethyl sulfoxide (CAS NO.67-68-5) is a by-product of kraft pulping. The sulfide used as a nucleophile also attacks the lignin, producing methanethiol and Dimethyl Sulfide, which is oxidized to DMSO. Suppliers of DMSO are Arkema, Toray or the Gaylord Chemical Corporation.
It reacts with methyl iodide to form a sulfoxonium salt [(CH3)3SO]I, which can be deprotonated with sodium hydride to form the sulfur ylide:
(CH3)2SO + CH3I → [(CH3)3SO]I
[(CH3)2SO ]I + NaH → [(CH3)2CH2SO + NaI + H2
