Description

General description

Dimethyl sulfoxide is an amphipathic molecule, soluble in both aqueous and organic solvents. It is commonly used as an aprotic solvent and also as a reagent in organic synthesis.

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.

Packaging

100, 500, 500 mL

1, 1, 2.5, 4 L in glass bottle

5, 10 L in poly drum

230 kg

Note: D5879-1L in glass bottle /D5879-1L-D in poly bottle.

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. It is also useful for the oxidation of thiols and disulfides to sulfonic acids.

Caution

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
