Dimethyl sulfoxide /Cenke

Core Characteristics: 

1. Physical Properties
At room temperature, it is a colorless, transparent liquid with extremely high hygroscopicity. Except for petroleum ether, it is miscible with most organic solvents, including water, ethanol, acetone, benzene, and chloroform, and is often referred to as the “universal solvent.”
2. Chemical Properties
(1) Thermal Stability: Prolonged heating at the boiling point causes the decomposition of trace amounts of formaldehyde. Decomposition is accelerated under acidic conditions but inhibited in alkaline environments. During purification, vacuum distillation is typically employed while maintaining a pH of approximately 8, or sodium oxalate is added as a stabilizer.
(2) Oxidation-Reduction Properties: It can be oxidized to dimethyl sulfoxide and reduced to a sulfide.
(3) Halogenation Reactions: Reacts with halogens to form halogenated derivatives; for example, it reacts with chlorine to form CH₃SOCH₂Cl.
(4) Other Reactions: Reacts with thiosulfonyl chloride, hydrochloric acid, thiols, and other compounds; it can also serve as a reaction medium.
3. Main Applications
(1) Pharmaceutical field: It can serve as a drug solvent and osmotic agent. It possesses anti-inflammatory, analgesic, and blood circulation-promoting properties, as well as wound-healing effects. It can also function as a platelet cryopreservative and osmotic protective agent, and is used in preliminary drug screening experiments.
(2) Chemical Industry: It serves as a highly efficient solvent for organic synthesis and acts as a reaction medium in organic catalytic reactions; it is also used as a dyeing solvent, decolorizing agent, and dye carrier for synthetic fibers, as well as an absorbent for recovering acetylene and sulfur dioxide.
(3) Pesticide Industry: It can be used as a penetrant and synergist to enhance the effectiveness of pesticides.
(4) Electronics Industry: It can be used as a cleaning agent and release agent for electronic components.
(5) Coatings Industry: It can be used as a solvent, resin solvent, and antifreeze agent. It can also be combined with alkali or nitric acid to serve as a paint stripper for removing various paint films, including those made of epoxy resin.

Grades and Specifications: Industrial grade.

The product strictly complies with the GB/T 2961-2014 national standard, accompanied by a complete set of MSDS, commodity inspection reports, and hazardous packaging certificates, and meets EU REACH import and export requirements.
