Description:

  • Solvent: DMSO is an excellent solvent, capable of dissolving a wide range of organic and inorganic compounds. It can dissolve both polar and non-polar substances, making it versatile in a variety of applications.
  • Hygroscopic: DMSO is hygroscopic, which means it rapidly absorbs moisture from the atmosphere. This property can be advantageous in certain processes but also requires proper storage and handling to prevent contamination.
  • High Boiling Point: DMSO has a high boiling point of 189°C (372°F), allowing it to be used in high-temperature applications.
  • Low Toxicity: DMSO is considered to have low toxicity in most applications. However, it can enhance the absorption of certain substances through the skin, so proper precautions need to be taken.
  • Medical and Pharmaceutical Applications: DMSO is used in the pharmaceutical industry as a solvent and as a vehicle for drug delivery. It penetrates the skin and has anti-inflammatory and analgesic properties, making it suitable for topical treatments.
  • Industrial and laboratory use: DMSO is useful in a variety of industrial processes, for example as a reaction solvent in polymer production, as a solvent in organic synthesis, and as a cryoprotectant for cell preservation.
  • Research and scientific studies: DMSO is commonly used in research laboratories for cryopreservation of cells, as a solvent for chemical reactions, and as a cryoprotectant in protein structure studies.
