Property:Dimethyl sulfoxide (DMSO) is organic sulfide compound. It is colorless, odorless and transparent liquid at room temperature. It is a kind of moisture absorption combustible liquid. It has characteristics of high polarity, high boiling point, non-proton, mixed with water, low toxicity and good heat stability. It is soluble in ethanol, propanol, benzol, chloroform and many organic matters. It was known as “Omnipotent Solvent” Boiling point(760mm):189°C ;Density(25°C) 1.101 g/mL; permittivity (20°C):46.68 ;Freezing point:18.4°C ;Refractive index(n20°/D) :1.4790;Viscosity (cps) 20°C:2.24

Usage:Dimethyl sulfoxide (DMSO) can be widely used as solvent and reaction reagent, especially as processing solvent and laddering solvent in the acrylonitrile polymerization reaction, and synthetic solvent and laddering solvent for polyurethane, also for polyamide, polyimide, polysulfone resin, aromatic hydrocarbon, butadiene and Chlorofluoroaniline etc. Moreover, Dimethyl sulfoxide (DMSO) has the functions of anti-inflammatory analgesic, diuresis and mitigation. It is added in dugs as analgesia ingredient. It also known as “Omnipotent Drug
