DMSO, also known as dimethyl sulfoxide, is a fascinating and versatile solvent used in a variety of applications in laboratories and industry. As a highly polar aprotic solvent with unique properties, DMSO has a wide range of uses and is indispensable in many fields.

Properties and applications of DMSO

DMSO is a colorless, oily liquid with a characteristic odor. It is distinguished by a number of remarkable properties:

• High polarity: DMSO is a highly polar solvent capable of dissolving a variety of polar and nonpolar substances. This makes it a versatile solvent for chemical syntheses and extractions.

• Aprotic: DMSO contains no hydrogen atoms that could act as proton donors. Therefore, it is excellent for reactions where protons play a role.

• High solvency: DMSO can dissolve a wide variety of organic and inorganic compounds in high concentrations, making it a powerful solvent.

• Good penetration ability: Due to its lipophilicity and polarity, DMSO can penetrate cell membranes and tissues well. This makes it an interesting carrier for active substances in medicine.

• Low vapor pressure: DMSO has a relatively low vapor pressure, which facilitates handling and storage.

Due to these properties, DMSO is used in numerous application areas:

Chemical syntheses and extractions

In organic synthesis, DMSO is often used as a solvent for reactions involving polar or ionic intermediates. It is also excellent for extractions to isolate active substances or other compounds from complex matrices.

Medical applications

In medicine, DMSO is used as a carrier for active substances due to its penetration ability to efficiently deliver them into the body. Additionally, it is used as an active agent itself, for example in the treatment of pain, inflammation, or varicose veins.

Technical applications

In technology, DMSO is used as a solvent for polymers, adhesives, and coatings. It also plays an important role in the semiconductor industry for cleaning and surface treatment.

Research and development

In research laboratories, DMSO is an indispensable tool for a variety of applications, from cell culture to analytics to preparative separations.

Safety and handling of DMSO

Although DMSO is considered safe in many applications, some precautions must be observed when using it:

Skin absorption and odor transfer

DMSO can be absorbed through the skin and transfer its characteristic garlic odor. Although harmless, this can be unpleasant. Therefore, it is important to avoid skin contact and wear appropriate protective equipment.

Storage and Transport

DMSO should be stored protected from moisture and heat sources, as decomposition reactions may occur otherwise. Applicable hazardous materials regulations must be observed during transport.

Disposal

Empty DMSO containers and residues must be disposed of as hazardous waste. Improper disposal can lead to environmental damage.

Conclusion

DMSO is a fascinating and versatile solvent with a wide range of applications in laboratories and technology. Its unique properties make it a valuable tool for chemists, medical professionals, and engineers. However, some safety aspects must be considered when using DMSO to minimize risks to humans and the environment.
