Top 5 Industrial Uses of DMSO CAS 67-68-5
Chemical and Laboratory Applications
DMSO is used as a solvent in the chemical and laboratory industries because of its high polarity and ability to dissolve a wide variety of compounds. It can dissolve both polar and non-polar substances, which is rare. For example, in organic synthesis, Dimethyl Sulfoxide DMSO can be used to dissolve reactants and facilitate chemical reactions. It can also be used to purify certain compounds through processes like crystallisation.
electrolyte solvent
The DMSO is also used in electrochemistry. It can act as an electrolyte solvent, helping to conduct electricity in electrochemical cells. This property is crucial in the development of batteries and other electrochemical devices. In addition, in nuclear magnetic resonance (NMR) spectroscopy, DMSO can be used as a solvent. Its low freezing point and high boiling point make it suitable for a wide range of temperature-dependent NMR experiments.
Pharmaceutical and Medical Applications
One of the most well-known medical uses of dimethyl sulfoxide is its anti-inflammatory properties. It has been used topically to relieve pain and reduce swelling in conditions such as arthritis. When applied to the skin, DMSO can penetrate the tissue quickly and carry other medications with it, which enhances their effectiveness.
Industrial applications
In industry, it is used in the production of polymers. It acts as a solvent for polymer synthesis, dissolving monomers and facilitating the polymerisation process. This is important in the manufacture of plastics, fibres, and other polymer-based products.
Cosmetic applications
In the cosmetics industry, dimethyl sulfoxide (DMSO) is used for its moisturising and skin-conditioning properties. It helps keep the skin hydrated and soft. It can also be used to carry other cosmetic ingredients into the skin more effectively. This makes it a valuable ingredient in skin creams, lotions and other beauty products.
