Product Application
Dimethyl sulfoxide is a highly important aprotic polar solvent that is soluble in both water and organic solvents. It is widely used as a solvent and reaction reagent, with a high selective extraction capacity.
It is widely used as a solvent and reaction reagent, particularly as a processing solvent and drawing solvent in acrylonitrile polymerization. It is also used as a solvent in the synthesis and drawing of polyurethane, polyamide, polyimide, and polysulfone resins, as well as a solvent for aromatics, butadiene extraction, and the synthesis of chlorofluoraniline.
In organic synthesis, it is also used in many oxidation reactions. At the same time, it is increasingly used in the microelectronics industry. In medicine, it is primarily used in local analgesics, drug carriers, anti-inflammatory drugs, and antioxidants.
In the field of electronics, It is used as a developer and stain remover in the manufacture of integrated circuits.
