Dimethyl sulfoxide USP DMSO CAS 67-68-5

Dimethyl sulfoxide (DMSO) is an aprotic solvent. Therapeutic and toxic molecules that are insoluble in water are usually soluble in DMSO. Liquid nitrogen in combination with cryoprotectants such as DMSO is a widely used method for cell preservation. DMSO has been used to prepare reserve solutions for a variety of molecules and also serves as a control for these molecules. It has been used in cell migration tests of lytic cells after migration. DMSO tested by BPC can also meet the requirements of biotechnology and tissue engineering applications.
Features and advantages:

Ready-to-use sterile filtration products conveniently packaged in spacer nut amber bottles. Meet the requirements of USP and EP testing

Attention:

지나치게 냉각되기 쉽고 상온에서 천천히 녹고 고화되는 제품은 자체에 영향을 주지 않고 상온에서 다시 액화될 수 있습니다.
안정:

1. Colorless liquid, flammable, almost odorless, with bitter taste. The product is a highly polar organic solvent, can be mixed with water in any proportion, in addition to petroleum ether, can dissolve general organic solvents. At 20℃ can absorb hydrogen chloride 30% (weight); Nitrogen dioxide 30% (weight); Sulfur dioxide 65% (weight). Strong hygroscopic, at 20 ° C, when the relative humidity is 60%, it can absorb 70% of its own weight from the air. The product is a weak oxidizing agent, and the non-aqueous dimethyl sulfoxide is non-corrosive to metals. To iron when hydrated; Metals such as copper are corrosive, but not aluminum. Stable to alkali. Heating in the presence of acid produces a small amount of methyl mercaptan; Formaldehyde; Dimethyl sulfur; Mesylate and other compounds. There is decomposition phenomenon at high temperature, and it can react violently in the case of chlorine, burning in the air and emitting a light blue flame.

Chemical properties: Reduction of dimethyl sulfoxide to methyl sulfide. Oxidized to dimethyl sulfone by strong oxidant;

2. When dimethyl sulfoxide is in contact with acyl chloride such as cyanuryl chloride, benzoyl chloride, acetyl chloride, benzoyl iodide chloride, thionyl chloride, thionyl chloride, phosphorus trichloride, etc., intense exothermic decomposition reaction occurs. It combines with nitric acid to form (CH3)2SO·NHO3. Dimethyl sulfoxide can be regenerated by interaction with barium carbonate. React with concentrated hydroiodic acid to form dimethyl sulfur compound.

3. Dimethyl sulfoxide has water absorption and needs to be dried before use.

Freezing point: 18.4℃
