Dimethyl Sulfoxide (DMSO), with the chemical formula C₂H₆OS, is a clear, colorless, hygroscopic liquid with a slight garlic-like odor. It is an organosulfur compound known for its excellent solvent properties, capable of dissolving both polar and non-polar compounds. DMSO is widely used in pharmaceutical, biomedical, chemical, and electronic industries due to its high purity and low toxicity. In pharmaceuticals, it serves as a carrier for drug delivery; in industrial applications, it is used as a reaction solvent, paint stripper, and cryopreservative.
