| 描述 | Biochem/physiol Actions
DMSO is a highly polar substance that can be used as an industrial solvent for organic and inorganic chemicals. It is also used as a protectant during cold storage of living cells.[4][5] It is also useful for the oxidation of thiols and disulfides to sulfonic acids.[6]
Caution
容易过度冷却，并在室温下缓慢融化固化的产品放在室温下可以再次液化，对其本身无影响。
Application
DMSO has been used as a medium to prepare a chemiluminescence reagent that can be a substitute to commercially-available enhanced chemiluminescence kits for use in immunoblotting technique.[10]
General description
Dimethyl sulfoxide is an amphipathic molecule, soluble in both aqueous and organic solvents.[7] It is commonly used as an aprotic solvent[8] and also as a reagent in organic synthesis.[9]
