Dimethyl Sulfoxide

Dimethyl sulfoxide is a sulfur-containing organic compound, the CAS number is: 67-68-5, the molecular formula is: C2H6OS. It is a colorless, odorless, transparent liquid at room temperature, has the characteristics of high polarity, high boiling point, good thermal stability, aprotic, and miscible with water, can dissolve in most organic substances such as ethanol, propanol, benzene and chloroform, and is known as a “universal solvent”. When heated in the presence of acid, it will produce a small amount of methyl mercaptan, formaldehyde, dimethyl sulfide, methanesulfonic acid and other compounds. It decomposes at high temperatures and reacts violently with chlorine, burning in the air with a light blue flame.

Dimethyl Sulfoxide can be used as an organic solvent, reaction medium and organic synthesis intermediate; it can also be used as a dyeing solvent, de-dyeing agent, dyeing carrier for synthetic fibers, and an absorbent for recovering acetylene and sulfur dioxide.
