Product Description
Dimethyl sulfoxide (DMSO) is a colorless, odorless, slightly bitter transparent liquid with strong polarity and a high boiling point (189°C). It is miscible with water, ethanol, acetone, and various other organic solvents, exhibiting stable chemical properties and exceptional permeability.
As a vital chemical raw material and solvent, it finds extensive applications in pharmaceuticals, pesticides, electronics, polymer materials, and other fields. Particularly in medicine, it serves as a transdermal absorption enhancer, while in industry, it functions as an excellent non-protonic polar solvent.
