General description
Dimethyl Sulfoxide (DMSO) contains both highly polar and apolar groups, which impart it an amphipathic character. It can dissolve in both aqueous and organic solvents. It is a commonly used solvent in hydrophobic pharmaceutical agents, exhibiting effective hydroxyl radical scavenging ability.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here
Application
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
DMSO may be used as an analytical standard for the determination of the analyte in environmental samples by gas chromatography (GC) technique.
Dimethyl sulfoxide may be used as a molecular probe in the detection and analysis of hydroxyl radicals generated in advanced oxidation processes using high performance liquid chromatography(HPLC).
