Applications & Uses

Uses

Use as high temperature solvent inorganic and organic substances, organic chemical raw materials, food additives and health products raw materials, also used as gas chromatography stationary phase (maximum use temperature 30 ℃, acetone as solvent) and analytical reagents.

Uses

Dimethyl sulfone is used as a high-temperature solvent for both inorganic and organic substances. It acts as an intermediate as well as medium in organic synthesis. It plays an important role as a carbon source by the airborne bacteria Afipia. It is also employed as an extraction solvent for the separation of aromatic compounds like benzene, toluene and xylenes from aliphatic hydrocarbons. Further, it is used in the polymerization process. It finds application in pharmaceuticals, agrochemicals, paint and coating materials.

Uses

Dimethyl sulfone is a high tempereture solvent for many inorganic and organic substances,it is used as antiinflammatory, antiproliferative, antiparasitic.
