Dimethyl sulfoxide

　　Main Uses

　　Solvent Field:

　　As a "universal solvent," it is widely used in chemical synthesis and organic reactions to dissolve insoluble substances (such as steroid compounds and polymer materials).

　　In the electronics industry, it is used to clean semiconductor chips and circuit boards, removing oil stains and impurities.

　　In laboratories, it is used for sample dissolution and extraction separation (e.g., extracting active ingredients from plants).

　　Pharmaceutical and Biological Fields:

　　As a transdermal absorption enhancer, it helps drugs penetrate the skin and enter the body (e.g., added to certain topical ointments and patches to enhance efficacy).

　　Used in the preparation of cell cryopreservation solutions to reduce cell damage during the freezing process (common in biological laboratories and medical fields).

　　It has been attempted for the treatment of arthritis and local inflammation, but its irritancy has limited some applications.

　　Chemical and Material Fields:

　　Participates as a reaction medium in polymerization reactions (e.g., synthesizing specialty materials like polyimides and polyphenylene sulfides).

　　In the dye industry, it is used to dissolve dyes and improve dyeing efficiency.

　　Used as an intermediate for synthesizing other sulfur-containing compounds (such as dimethyl sulfone).

　　Other Uses:

　　In agriculture, it is used as a pesticide adjuvant to enhance the penetration and absorption of pesticides on plant surfaces.

　　In the electroplating industry, it is used to improve coating quality and increase the solubility of metal ions.
