Uses

Dimethyl sulfoxide (CAS NO. 67-68-5) is an important polar aprotic solvent. It is widely used to strip photoresist in TFT-LCD 'flat panel' displays and advanced packaging applications (such as wafer-level packaging / solder bump patterning). It also used in biopresevation especially stem cell banking. It is predominantly used as a topical analgesic, a vehicle for topical application of pharmaceuticals, as an anti-inflammatory, and an antioxidant.

Production

Dimethyl sulfoxide (CAS NO.67-68-5) is a by-product of kraft pulping. The sulfide used as a nucleophile also attacks the lignin, producing methanethiol and Dimethyl Sulfide, which is oxidized to DMSO. Suppliers of DMSO are Arkema, Toray or the Gaylord Chemical Corporation.
It reacts with methyl iodide to form a sulfoxonium salt [(CH3)3SO]I, which can be deprotonated with sodium hydride to form the sulfur ylide:
(CH₃)₂SO + CH₃I → [(CH₃)₃SO]I
[(CH₃)₂SO ]I + NaH → [(CH₃)₂CH₂SO + NaI + H₂
