Dimethyl Sulfoxide (DMSO) C2H6OS CAS 67-68-5 - China Suppliers & Factory Direct Supply
Dimethyl sulfoxide (DMSO) is a versatile organosulfur compound represented by the formula (CH3)2S=O. As a leading product among China suppliers, DMSO is the most widely used sulfoxide in commercial applications. This colorless liquid serves as a crucial polar aprotic solvent, effectively dissolving both polar and nonpolar substances and readily mixing with various organic solvents and water. Notably, DMSO features a relatively high boiling point, making it an ideal choice for numerous industrial applications. When absorbed through the skin, DMSO is metabolized into compounds that may leave a garlic-like taste in the mouth. Chemically, its structure exhibits idealized Cs symmetry and follows a trigonal pyramidal geometry, typical of three-coordinate S(IV) compounds, with an electron pair on the tetrahedral sulfur atom. Our factory ensures the highest quality DMSO for all your industrial needs.
Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound, with the English name Dimethylsulfoxide, and its molecular formula is (CH3)2SO. At room temperature, it is a colorless and odorless transparent liquid with hygroscopicity and flammability. It has the characteristics of high polarity, high boiling point, non-protonic nature, and miscibility with water. It has extremely low toxicity and good thermal stability.
It does not mix with alkanes and can dissolve in most organic substances such as water, ethanol, propanol, ether, benzene, and chloroform. It is hailed as the "universal solvent". Among the commonly used organic solvents, it is the one with the strongest dissolving ability.
It can dissolve a large portion of organic substances, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve a solute equivalent to 50-60% of its own weight (while other common solvents can only dissolve 10-20%). Therefore, it is very important in sample management and high-speed drug screening. Under certain conditions, when DMSO comes into contact with acyl chlorides, an explosive reaction will occur.
Frequently Asked Questions
What are the primary physical properties of DMSO?
DMSO is a colorless, odorless, and transparent liquid at room temperature. It is hygroscopic, flammable, possesses high polarity, a high boiling point, and is non-protonic.
Why is DMSO referred to as the "Universal Solvent"?
It is called the "universal solvent" because it has the strongest dissolving ability among common organic solvents, capable of dissolving a wide range of organic substances, inorganic salts, and gases.
How does the solubility of DMSO compare to other solvents?
DMSO can dissolve solutes equivalent to 50-60% of its own weight, which is significantly higher than other common solvents that typically only dissolve 10-20%.
What types of substances can DMSO dissolve?
It can dissolve carbohydrates, polymers, peptides, many inorganic salts, gases, and most organic substances like ethanol, propanol, ether, benzene, and chloroform.
Are there any safety risks associated with DMSO?
While it has extremely low toxicity and good thermal stability, an explosive reaction can occur if DMSO comes into contact with acyl chlorides under certain conditions.
Is DMSO miscible with all liquids?
DMSO is miscible with water and most organic substances, but it does not mix with alkanes.
