Dimethyl sulfoxide, 99+%, Thermo Scientific Chemicals

Description

Dimethyl Sulfoxide (DMSO) is used as a solvent for chemical reactions involving salts, most notably in Finkelstein reactions and in other nucleophilic substitutions. It is also used in antifreeze or hydraulic fluids and utilized in the oxidation of thiols and disulfides to sulfonic acids.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Dimethyl Sulfoxide (DMSO) is used as a solvent for chemical reactions involving salts, most notably in Finkelstein reactions and in other nucleophilic substitutions. It is also used in antifreeze or hydraulic fluids and utilized in the oxidation of thiols and disulfides to sulfonic acids. It is also used as a cryoprotectant and is added to cell media to reduce ice formation and thereby prevent cell death during the freezing process.

Solubility
Miscible with water, ethanol, ether, benzene, chloroform and acetone.

Notes
Hygroscopic. Incompatible with acid chlorides, phosphorus halides, strong acids, strong oxidizing agents and strong reducing agents.
