Dimethysulfoxide (DMSO)
Grade
ACS Grade
Description
Dimethyl sulfoxide (DMSO) is a highly polar organic reagent that has exceptional solvent properties for organic and inorganic chemicals. DMSO can be used in organic synthesis; one of the applications is the oxidation of thiols and disulfides to sulfonic acids. Other applications include the hydrolysis of epoxides, the thioalkylation of phenols, and the oxidation of primary alcohols, primary halides, and esters of primary alcohols to aldehydes.
The compatibility of DMSO with various materials is listed below:
- Compatible: LDPE, HDPE, polypropylene, PPCO (polypropylene copolymer), polymethylpentene, nylon, Teflon FEP
- Moderately compatible: polystyrene, ECTFE/ETFE
- Incompatible: polysulfone, flexible and rigid PVC tubing, polycarbonate
Note
*DMSO can be supercools easily and remelts slowly at room temperature. The product may arrive as a solid instead of a liquid. The solidified product can be reliquified by warming to room temperature without detriment to the product.
**DMSO is stable up to 100°C in alkaline, acidic and neutral conditions. At temperatures approaching its boiling point, DMSO is stable in neutral or alkaline conditions.
***It is recommended to use a Teflon or nylon membrane to prepare a sterile filtered DMSO solution. Cellulose acetate membranes are not recommended.
