Physical Properties of Dimethyl Sulfoxide (DMSO)

Dimethyl Sulfoxide, commonly known as DMSO and identified by CAS number 67-68-5, is an organic solvent with remarkable physical properties. It is a clear, colorless liquid with a slight sulfur odor. DMSO has a melting point of 18.5°C and a boiling point of 189°C. Its high polarity and ability to dissolve a wide range of organic and inorganic compounds make it a versatile solvent. DMSO has a density of about 1.1 g/cm³ at 20°C and exhibits high thermal stability and low viscosity. It is hygroscopic, meaning it can readily absorb moisture from the environment.

Applications of Dimethyl Sulfoxide (DMSO)

DMSO is widely used in the pharmaceutical industry, particularly as a penetration enhancer in topical medications. Its ability to penetrate the skin and carry other substances with it improves the efficacy of active ingredients. Additionally, it is used in drug formulations to increase the solubility of poorly soluble compounds.

Another significant application of DMSO is in the cryopreservation of cells and tissues. Due to its protective properties against cold damage, it is commonly used as a cryoprotectant. DMSO helps prevent the formation of ice crystals, thereby maintaining the integrity and functionality of cells during freezing and thawing processes.

In the chemical industry, DMSO serves as a versatile solvent for organic reactions and polymerizations. It is often used in the production of polymers, resins, and other chemicals because it can effectively dissolve a wide range of substances. Its stability and non-volatile nature make it a preferred solvent in various industrial processes.

DMSO is used in human and veterinary medicine as an anti-inflammatory and pain-relieving agent. It is often applied in the form of gels or solutions to treat muscle pain, joint inflammation, and other inflammatory conditions. Its analgesic properties and ability to reduce inflammation make it a valuable component in pain management therapies.

Dimethyl Sulfoxide (DMSO, CAS No. 67-68-5) is a chemical raw material with outstanding physical properties that make it indispensable in many industries. From the pharmaceutical industry to cryopreservation, industrial solvents, and medical applications, the versatility and efficacy of DMSO make it a crucial component in numerous processes and products.
