China Factory Supply 99% Dimethyl Sulfoxide/DMSO CAS 67-68-5
Dimethylsulfoxide (DMSO) is a sulfur-containing organic compound, English name Dimethylsulfoxide, molecular formula (CH3)2SO, at room temperature is colorless and odorless transparent liquid, with hypersonic flammable liquid, both high polarity, high boiling point, aprotic, water mismissibility characteristics, very low toxicity, good thermal stability, It is not mixed with alkanes, and can dissolve in water, ethanol, propanol, ether, benzene and other most organic matter, known as "universal Chemicalbook solvent". It is one of the most powerful organic solvents in common use. It can dissolve most organic matter, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve solutes equal to 50-60% of its weight (other common solvents can only dissolve 10-20%), so it is important in sample management and high-speed drug screening. Under certain conditions, an explosive reaction occurs when dimethyl sulfoxide comes into contact with an acyl chloride.
Appearance: colorless transparent liquid with strong irritating smell
