The dimethyl sulfoxide (DMSO) produced by our company, also known as DMSO, is a national standard premium-grade product with a purity of 99.5%. It is an organic sulfur compound with the molecular formula C2H6OS. At normal temperatures, it is a colorless, odorless transparent liquid, a hygroscopic flammable liquid classified as a Category 3 hazardous chemical. Its CAS registry number is 67-68-5, with a melting point of 18.4°C, boiling point of 189°C, and flash point of 95°C. Under normal conditions, it is soluble in water, ethanol, propanol, benzene, chloroform, and most other organic solvents. It is widely used as a solvent and reaction reagent, exhibiting high selective extraction capabilities. Dimethyl sulfoxide itself has anti-inflammatory, analgesic, diuretic, and sedative effects. In the pharmaceutical industry, it can be directly used as a raw material and carrier for certain drugs. Known as a "panacea," it is often added as an active ingredient in pain-relief medications.
