What is Dimethyl Sulfoxide?

Dimethyl Sulfoxide CAS NO. 67-68-5 is an organosulfur compound with the chemical formula C₂H₆OS. It is a clear, colorless liquid that has a remarkable ability to dissolve a wide range of organic and inorganic substances. Originally derived as a byproduct of wood pulp processing, DMSO is now manufactur for use in industries ranging from medicine to agriculture. It is known for its ability to penetrate biological membranes, which gives it unique applications in both the medical and scientific fields.

Chemical Properties of DMSO

Dimethyl sulfoxide is a polar aprotic solvent, meaning it has no hydrogen atoms attached to its oxygen atom. This characteristic makes it an excellent medium for chemical reactions. Here are some of its notable chemical properties:

  • Polarity: Highly polar, making it a powerful solvent.
  • Chemical Stability: Resistant to oxidation and reduction under normal conditions.
  • Reactivity: It can act as a nucleophile in certain chemical reactions.

DMSO’s chemical properties are what make it such a valuable tool in chemical research and synthesis.

Physical Properties of DMSO

Here are some of the physical characteristics that make DMSO stand out:

  • Appearance: A clear, colorless liquid.
  • Boiling Point: Approximately 189°C (372°F).
  • Freezing Point: Around 18.5°C (65.3°F), where it solidifies into a crystalline structure.
  • Odor: Mild garlic-like smell.
  • Miscibility: Fully miscible with water and most organic solvents.

Its ability to mix seamlessly with other solvents makes it an essential component in various industries.

How is DMSO Produced?

DMSO is typically produce as a byproduct of the paper and wood pulp industry. Here’s a simplified overview of the production process:

  1. Raw Material: Lignin, a natural polymer in wood, is broken down.
  2. Oxidation: Sulfite pulping results in dimethyl sulfide (DMS).
  3. Processing: DMS is then oxidized to produce DMSO.

This sustainable production process is one of the reasons DMSO is widely available and relatively affordable.

Applications of DMSO

Medical Uses of DMSO

One of the most fascinating aspects of DMSO is its use in the medical field. It is FDA-approved for treating interstitial cystitis, a painful bladder condition. Additionally, it has been studied for its potential to reduce inflammation, relieve pain, and even carry drugs through the skin.
