Dimethyl Sulfoxide (DMSO), a versatile organosulfur compound with the chemical formula C2H6OS and CAS No. 67-68-5, stands as a cornerstone in various industrial, biological, and medical applications. This colorless liquid, first synthesized in 1866 by Alexander Zaytsev, gained prominence as an industrial solvent due to its unique properties. It is a highly effective polar aprotic solvent, capable of dissolving both polar and nonpolar compounds, and is remarkably miscible with a wide range of organic solvents as well as water. Its relatively high boiling point of 189°C (372°F) and a freezing point of 18.5°C (65.3°F) further contribute to its utility in diverse environments.

Industrially, DMSO's applications are extensive and impactful. It serves as an excellent medium for extracting arene and is widely used in chemical reactions involving resins and dyes. Its role extends to acrylic polymerization and spinning processes, as well as an extraction solvent for separating alkanes and arenes. Furthermore, DMSO acts as a reaction medium for butadiene extraction, a solvent for acrylic fibers and plastics, and a key component in organic and synthetic dye production. In agriculture, a small addition of DMSO to pesticides can significantly improve their efficacy by facilitating better penetration into plants. It is also employed as a dye solvent, dye removing agent, and dye carrier for synthetic fibers, and finds use as an absorbent for recycling acetylene, a modifier for synthetic fibers, an antifreeze agent, and an extractant for rare metals. Its analytical purity makes it suitable as an analytic solvent and fixing agent in gas chromatography, and for analyzing UV spectra.

Beyond industrial use, DMSO plays a crucial role in the biological and medical fields. It is a well-known cryoprotectant, vital for preserving biological cells and tissues by reducing ice crystal formation during freezing, thereby preventing cell death. This property is particularly critical for the long-term storage of sensitive materials like embryonic and hematopoietic stem cells. In molecular biology, DMSO is invaluable in the polymerase chain reaction (PCR) to inhibit secondary structures in DNA templates, ensuring more efficient amplification. It is also utilized as a versatile solvent for in vitro and in vivo drug testing, capable of dissolving a broad spectrum of compounds—both polar and nonpolar—which is essential for high-throughput screening programs and maintaining stable stock solutions of test compounds. Its compatibility with water and cell culture media, coupled with its high boiling point, enhances the accuracy of experimental concentrations.

The medical applications of Dimethyl Sulfoxide are continuously explored. While its most notable FDA-approved use is for the symptomatic relief of interstitial cystitis, it has also been investigated as a topical analgesic, an anti-inflammatory agent, and an antioxidant. Its unique ability to penetrate biological tissues, including skin, without causing damage makes it an excellent vehicle for transdermal drug delivery systems, often compounded with other medications like antifungals to enhance penetration. Furthermore, in interventional radiology, DMSO serves as a solvent for specific embolic agents used in therapeutic procedures.
