Used for aromatic extraction, resin and dye reaction medium, acrylic polymerization, wire drawing solvent, etc

Can be used as organic solvent, reaction medium and organic synthesis intermediates. Extremely versatile.

Used as an analytical reagent and a stationary solution for gas chromatography, also used as a solvent in ultraviolet spectrum analysis.

Use for antifreezing agent.

DMSO is also a osmotic protective agent that can reduce the freezing point of cells, reduce the formation of ice crystals, the damage of free radicals to cells, and change the permeability of biofilms to electrolytes, drugs, poisons and metabolites.
