What are the properties of DMSO (CAS:67-68-5) solvent?

dmso solvent properties

Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound with the molecular formula C₂H₆OS, exhibiting multiple important properties and a wide range of applications. The following provides a detailed introduction to dimethyl sulfoxide:

DMSO solvent physical properties

• Appearance: Colorless, odorless, transparent liquid at room temperature with hygroscopic properties.
• Melting point: 18.4°C
• Boiling Point: 189°C
• Density: 1.100 kg/m³
• Flash Point: 95°C
• Solubility: Soluble in water, ethanol, acetone, acetaldehyde, pyridine, ethyl acetate, and various organic solvents. As a key non-protonic polar solvent, it is often referred to as the "universal solvent."

DMSO solvent chemical properties

• Stability: DMSO solvent is relatively stable at room temperature but decomposes readily under high temperatures, sunlight exposure, or contact with oxygen.
• Reactivity: Heating in the presence of acids produces small amounts of methyl mercaptan, formaldehyde, dimethyl sulfide, and methanesulfonic acid. It reacts violently with chlorine and burns in air with a pale blue flame.
• Reduction Properties: DMSO solvent can be reduced to form dimethyl sulfide, while strong oxidizing agents oxidize it to dimethyl sulfone.

DMSO solvent Synthesis Methods

The primary synthesis methods for dimethyl sulfoxide include:

• Carbon disulfide and methanol method: Produced via oxidation reaction using methanol and carbon disulfide as raw materials.
• Hydrogen Peroxide Method: Reacts dimethyl sulfide with hydrogen peroxide using acetone as a buffer medium.
• Nitrogen Dioxide Method: Reacts methanol with hydrogen sulfide to form dimethyl sulfide, which is then oxidized with nitrogen dioxide to produce dimethyl sulfoxide.

DMSO solvent uses

• Organic Synthesis: DMSO dimethyl sulfoxide is a crucial polar solvent widely used in organic synthesis. It dissolves numerous organic compounds and facilitates the progression of chemical reactions.
• Pharmaceutical Applications: In the medical field, DMSO serves as a solvent and carrier for pharmaceuticals, aiding drug penetration into biological tissues. Additionally, it is employed in topical treatments for conditions such as arthritis.
• Biochemical Research: DMSO is frequently employed as a solvent or additive in biochemical research, including cell culture, protein purification, and analysis.
• Health Supplements and Cosmetics: Dimethyl sulfoxide liquid is occasionally incorporated into health supplements and cosmetics for its penetration properties and moisturizing effects.
• Industrial Applications: DMSO solvent also serves industrial purposes as a lubricant, solvent extractant, resin solvent, and additive.
