Dimethyl Sulfoxide with cas 67-68-5
Dimethyl sulfoxide, abbreviated as DMSO, is a polar non-protonic organic solvent. Its chemical formula is C₂H₆OS and its molecular weight is 78.13. At room temperature, it is a colorless and transparent liquid. Below 18.5℃, it will solidify into crystals. It can be infinitely miscible with water, alcohols, ketones, esters, aromatic hydrocarbons, etc. It has strong solubility for inorganic salts, organic intermediates, and polymers. It is commonly known in the industry as the “universal solvent”.

Application
1. The King of industrial solvents
Polymer materials: Dissolved polyacrylonitrile, polyurethane, etc., used for synthetic fiber spinning and resin processing
Coatings and paints: Dimethyl sulfoxide can improve leveling, enhance pigment dispersion, and reduce VOC emissions
In the electronics industry, Dimethyl sulfoxide DMSO is used as a photoresist solvent and cleaning agent in the manufacturing of semiconductors and PCBS
Extraction and separation: Efficient extraction of drugs, fragrances, natural products, etc
2. A versatile player in the medical field
Drug carriers: Enhance the solubility of poorly soluble drugs and promote drug absorption
Local administration: Dimethyl sulfoxide 67-68-5 takes advantage of its excellent permeability to carry drugs through the skin (referred to as a “transdermal enhancer “).
Anti-inflammatory and analgesic: Dimethyl sulfoxide DMSO is used as an adjunctive treatment for joint inflammation and muscle pain
Medical-grade applications: An important component of blood products and organ preservation solutions
3. Other important applications
In the agricultural field, Dimethyl sulfoxide DMSO is used as a pesticide enhancer and a plant cell protectant
Dye industry: Disperse dye solvents to enhance dyeing uniformity
Petrochemical industry: Lubricating oil additives, aromatic hydrocarbon extractants
Analytical Chemistry: An excellent solvent for spectral analysis and NMR determination
Dimethyl sulfoxide (1-10%) has been shown to accelerate strand renaturation and is believed to give the nucleic acid thermal stability against depurination. As a PCR cosolvent, dimethyl sulfoxide DMSO may help improve yields, especially in long PCR.
