Chemical Properties of DMSO
- Molecular formula: (CH₃)₂SO
- CAS number: 67‑68‑5
- Appearance: Colorless, hygroscopic liquid
- Boiling point: 189°C
- Polarity: High; aprotic
- Solubility: Miscible with water, alcohols, and many organic solvents
These properties allow DMSO to stabilize reactive intermediates, dissolve both polar and nonpolar compounds, and facilitate reactions that might not proceed in other solvents.
Common Uses in Organic Synthesis
Nucleophilic Substitution Reactions (SN2)
DMSO is ideal for SN2 reactions because it stabilizes the transition state and enhances nucleophilicity of anions.
Example: Alkyl halide + nucleophile → substitution product
Oxidation Reactions
DMSO is often used in combination with oxidizing agents (e.g., Swern oxidation) to convert alcohols to aldehydes or ketones.
Coupling and Condensation Reactions
Useful in reactions requiring polar aprotic conditions, such as aldol condensations and certain Michael additions.
Polymer and Material Chemistry
Dissolves polymers and resins for organic transformations or material processing.
Industrial Applications of DMSO Solvent
- Pharmaceutical Industry:DMSO has excellent permeability, allowing active ingredients to penetrate deeply into the skin. For this reason, it is widely used in topical pharmaceutical formulations. Its strong solubility for many compounds also makes it a key component in drug coatings and transdermal delivery systems.
- Pesticide Industry:During the processing of pesticide intermediates and formulations, DMSO's excellent solubility and penetration ability help improve pesticide efficacy and utilization. It is also used as a high-quality organic solvent to dissolve and dilute active pesticide ingredients.
- Electronics Manufacturing:Due to its strong solvency and high boiling point, DMSO is commonly used as a cleaning agent in electronics production, especially in the manufacturing of semiconductors and integrated circuits. Its chemical stability and thermal resistance make it suitable for high-precision cleaning applications.
- Other Industries:DMSO (CAS 67-68-5) also plays an important role in petrochemicals, fiber manufacturing, and dye & pigment production. As a premium solvent, it helps increase production efficiency and reduce energy consumption.
