Dimethyl Sulfoxide/DMSO CAS:67-68-5

Product Information

Dimethyl sulfoxide (DMSO), CAS No. 67-68-5, is a colorless, transparent, viscous liquid with the molecular formula C₂H₆OS. It is an important polar aprotic solvent with excellent solubility, permeability, and stability. It is miscible with water, ethanol, and most organic solvents, and is widely used in the chemical, pharmaceutical, electronics, and materials industries as a versatile raw material for industrial and research applications.

Properties

It is a colorless, transparent, viscous liquid with a slight bitter taste. It is miscible with water, ethanol, acetone, ether, benzene, chloroform, and other organic solvents, and can dissolve most organic and inorganic substances. It is known as a "universal solvent." It is stable at room temperature and under normal pressure, but decomposes when heated above 150°C, producing toxic gases such as dimethyl sulfide and formaldehyde. It has good permeability and can penetrate the skin, carrying other substances into the body.

Uses and Applications

Solvent

DMSO is an excellent polar aprotic solvent with strong solubility and compatibility. It can dissolve a variety of organic compounds (such as hydrocarbons, alcohols, ketones, and esters), inorganic compounds (such as salts and oxides), and polymers (such as proteins, cellulose, and resins). It is widely used in organic synthesis, pharmaceutical synthesis, and material preparation as a reaction solvent. It can improve reaction rates, increase product yield, and simplify separation and purification processes. In the pharmaceutical industry, it is often used as a solvent for drug extraction, purification, and formulation, especially for drugs that are difficult to dissolve in water or other common solvents, such as steroids, antibiotics, and anti-tumor drugs. In the chemical industry, it is used in the synthesis of dyes, pigments, and pesticides, as well as in the dissolution and processing of polymers such as plastics and fibers.

Medical and Pharmaceutical Applications

In the medical field, DMSO has multiple uses due to its good permeability and anti-inflammatory, analgesic, and anti-edema effects. It is often used as a transdermal absorption enhancer in topical preparations, promoting the penetration of drugs through the skin and improving local drug concentration, thereby enhancing therapeutic effects. It is widely used in the preparation of ointments, gels, and liniments for the treatment of arthritis, muscle pain, contusions, and burns. In addition, DMSO is also used in cell culture in the biological field, where it can protect cells from damage during freezing and thawing and improve cell survival rates. It is also used in the preservation of organs and tissues in clinical medicine.

Electrochemical Field

Due to its high polarity, high dielectric constant, and good solubility for electrolytes, DMSO is widely used as an electrolyte solvent in electrochemistry, such as in lithium-ion batteries, fuel cells, and electrolytic capacitors. It can improve electrolyte conductivity, stabilize the electrode interface, and enhance the cycle performance and safety of batteries. In addition, it is also used in the electroplating industry as a plating solution additive, which can improve the uniformity and brightness of the plating layer and enhance its adhesion to the substrate.

Other Uses

DMSO has a wide range of applications. In addition to the fields above, it is also used as a dehydrating agent, plasticizer, and antifreeze agent in the chemical industry. It can be used to dehydrate organic compounds and improve product quality. As a plasticizer, it can improve the flexibility and processability of plastics and rubber. As an antifreeze agent, it has a good antifreeze effect in low-temperature environments. In the textile industry, it is used as a dyeing assistant, which can improve the dye uptake rate and uniformity of fabrics. In the food industry, it is used as an extractant for food additives and natural products. In the environmental protection field, it is used to treat industrial wastewater and waste gas, which can effectively degrade organic pollutants and reduce environmental pollution.
