Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (C H 3) 2 S=O. This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high ...

DMSO is an important polar aprotic solvent. In cryobiology DMSO has been used as a cryoprotectant and is still an important constituent of cryoprotectant vitrification mixtures used to preserve organs, tissues, and cell suspensions.[Wikipedia]

This colorless liquid found immediate application as a polar, aprotic solvent miscible with water and able to dissolve an enormous catalog of polar and nonpolar small molecules. Since the 1860s, DMSO has been extensively studied in the chemical literature.

2024年12月16日 · DMSO is a highly polar organic liquid that is used widely as a chemical solvent and a free radical scavenger. It shows a range of pharmacological activity including analgesia and anti-inflammation. Because of its ability to penetrate biological membranes, it is used as a vehicle for topical application of pharmaceuticals.

2022年1月19日 · Dimethyl sulfoxide (DMSO) is a polar aprotic solvent that can dissolve a wide range of organic compounds. Because Sulfur and Oxygen on this structure are very electronegative and have a greater electron affinity, the electrons will be pulled towards the S and Oxygen side of the molecule, creating a partial negative charge on the top of the ...

2021年3月28日 · Dimethyl sulfoxide (or DMSO) is an organosulfur compound with the formula (CH 3) 2 SO. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.

As a polar aprotic solvent, DMSO can dissolve both polar and nonpolar compounds. This capability is a valuable asset in chemistry, where it's often necessary to dissolve various substances for different processes and reactions. Furthermore, DMSO's high boiling point (189°C or 372.2°F) makes it suitable for reactions that require high ...

DMSO is a very polar, aprotic solvent. DMSO has something in common with water. Water is very polar, with a polar O-H bond. DMSO is very polar, having a strongly polarized S-O bond. Water can hydrogen bond. DMSO is capable of accepting hydrogen bonds. That means DMSO can use its lone pairs to donate to protons on other molecules. However, DMSO ...

2008年5月6日 · In this paper, we will explore the issue of DMSO and DMSO2 polarities in terms of their computed structures, electronic properties and electrostatic potentials. We will also look at some of their intermolecular interactions, as a means of addressing their very high boiling points and their notable solvent capabilities.

Dimethyl Sulfoxide (DMSO) is a highly polar and water miscible organic liquid. It is essentially odorless, and has a low level of toxicity. DMSO is a dipolar aprotic solvent, and has a relatively high boiling point. Further below is a compilation of Physical Properties data, such as DMSO density and stability, for this useful solvent.
