WHY DMSO IS USED AS SOLVENT

Dimethyl sulfoxide (DMSO) is a versatile solvent that has been used in a wide variety of applications, from industrial to pharmaceutical. Its unique properties make it a valuable tool for many scientists and researchers. In this article, we will take a closer look at why DMSO is used as a solvent.

Properties of DMSO

DMSO is a colorless, odorless liquid that is soluble in water and many organic solvents. It has a high boiling point (189 °C) and a low melting point (-63 °C). DMSO is also a powerful aprotic solvent, meaning that it does not donate protons. This makes it a good solvent for reactions that involve ionic species.

Applications of DMSO

DMSO has a wide range of applications in both industry and research. Some of the most common uses of DMSO include:

1. Pharmaceutical Applications:

DMSO is used as a solvent for drugs and other pharmaceutical products. It is also used as a penetration enhancer, which helps drugs to penetrate the skin and reach their target tissues. DMSO has been shown to be effective in treating a variety of conditions, including pain, inflammation, and arthritis.

2. Industrial Applications:

DMSO is used in a variety of industrial applications, including the manufacture of plastics, textiles, and dyes. It is also used as a solvent in the extraction of metals and oils. DMSO is a good solvent for many types of polymers, and it is often used in the production of synthetic fibers.

3. Research Applications:

DMSO is a valuable tool for researchers in a variety of fields. It is used as a solvent for biochemical and biological studies. DMSO is also used to extract DNA and RNA from cells. DMSO can also be used to preserve biological samples.

Advantages of Using DMSO as a Solvent

There are several advantages to using DMSO as a solvent. These advantages include:

• High Solvating Power: DMSO has a high solvating power, meaning that it can dissolve a wide range of solutes. This makes it a useful solvent for a variety of applications.

• Aprotic Nature: DMSO is an aprotic solvent, which means that it does not donate protons. This makes it a good solvent for reactions that involve ionic species.

• Low Toxicity: DMSO is relatively non-toxic, making it a safe solvent to use. However, it is important to note that DMSO can be absorbed through the skin, so it is important to wear gloves when handling it.

Disadvantages of Using DMSO as a Solvent

There are several disadvantages to using DMSO as a solvent. These disadvantages include:

• High Boiling Point: DMSO has a high boiling point, which can make it difficult to remove from solutions.

• Odor: DMSO has a strong odor that some people find unpleasant.

• Cost: DMSO is a relatively expensive solvent.

Conclusion

DMSO is a versatile solvent with a wide range of applications. It is a good solvent for many types of solutes, and it is also aprotic and relatively non-toxic. However, DMSO does have some disadvantages, such as its high boiling point, odor, and cost.
