It is a colourless liquid and an important polar aprotic solvent which dissolves both polar and non-polar compounds and is miscible in a wide range of organic solvents and water.

Consistent Quality: We carefully source Dimethyl Sulfoxide to ensure reliable and consistent performance, ensuring reproducibility.

Frequent Uses

Semiconductor Manufacturing

Utilised in microelectronics for cleaning and photoresist stripping due to its ability to dissolve residues without damaging sensitive components.

Gas Scrubbing

Often implemented into processes to absorb and remove sulphur compounds from gas streams, improving air quality and reducing emissions.

Organic Synthesis

DMSO is a useful source of carbon in organic synthesis. It can be used as an oxidant for alcohols.
