Dimethyl Sulfoxide (DMSO) C2H6OS CAS:67-68-5 - High-Quality China's Leading Suppliers & Factory
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.
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.
What is Dimethyl Sulfoxide (DMSO)?
Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound with the molecular formula (CH3)2SO. At room temperature, it is a colorless, odorless, transparent liquid characterized by hygroscopicity, flammability, high polarity, a high boiling point, and a non-protonic nature.
Why is DMSO referred to as the "universal solvent"?
DMSO is hailed as the "universal solvent" because it possesses the strongest dissolving ability among commonly used organic solvents. It can dissolve a large portion of organic substances, including carbohydrates, polymers, peptides, as well as many inorganic salts and gases.
How much solute can DMSO dissolve compared to other solvents?
DMSO has an exceptionally high dissolving capacity, allowing it to dissolve a solute equivalent to 50-60% of its own weight. In comparison, other common solvents typically can only dissolve 10-20% of their weight.
What are the solubility characteristics of DMSO with other substances?
DMSO is miscible with water and can dissolve in most organic substances, such as ethanol, propanol, ether, benzene, and chloroform. However, it does not mix with alkanes.
Are there any safety hazards or explosive risks associated with DMSO?
Yes, DMSO is flammable and, under certain conditions, will undergo an explosive reaction when it comes into contact with acyl chlorides.
Why is DMSO important in laboratory sample management and drug screening?
Due to its extremely strong dissolving capacity and ability to dissolve high concentrations of organic substances, peptides, and polymers, DMSO plays a crucial role in sample management and high-speed drug screening.
