Products Description of Dimethyl Sulfoxide-d6 CAS#2206-27-1
The purity of commercially available deuterated dimethyl sulfoxide reagents is typically around 99.5%, with water and dimethyl sulfone being the main impurities. Deuterated dimethyl sulfoxide is a sulfur-containing organic compound that appears as a colorless, odorless, transparent liquid at room temperature.
It is a hygroscopic and flammable liquid with high polarity, a high boiling point, good thermal stability, and aprotic properties. It is completely miscible with water and soluble in most organic solvents, including ethanol, propanol, and chloroform. Due to its excellent solvency, it is often referred to as a "universal solvent."
Deuterated dimethyl sulfoxide is widely used as a solvent and reaction reagent, particularly as a processing and spinning solvent. Its applications include polyurethane synthesis and spinning, as well as the synthesis of polyamide, polyimide, and polysulfone resins. It is also used as an extraction solvent for aromatic hydrocarbons and butadiene and as a solvent in the synthesis of chlorofluoroaniline. In addition, deuterated dimethyl sulfoxide is widely used in the pharmaceutical industry.
