Dimethyl Sulfoxide (DMSO) is a high-performance organic solvent widely used in chemical, pharmaceutical, and industrial applications. Its unique combination of physical and chemical properties makes it one of the most versatile solvents on the market.
Basic Information
Chemical Name: Dimethyl Sulfoxide
Synonyms: Methyl sulfoxide; Dimethyl sulfoxide
CAS Number: 67-68-5
Molecular Formula: C₂H₆OS
Molecular Weight: 78.13 g/mol
Key Properties of Industrial DMSO Solvent:
1. Excellent Solubility: DMSO (Dimethyl Sulfoxide) is often called a "universal solvent" because it can dissolve a wide variety of organic and inorganic substances, including poorly soluble polymers (such as cellulose and plastics), salts, and resins.
2. Physical State and High Boiling Point: DMSO is a colorless, transparent, and virtually odorless liquid at room temperature. Its boiling point is as high as approximately 189°C, making it suitable for high-temperature reactions and reducing vapor-related risks.
3. High Polarity: As a dipolar aprotic solvent, it has a high dielectric constant (approximately 46.7 at 20°C), making it an ideal solvent for ionic reactions.
4. High Freezing Point: DMSO has a high freezing point (18.45°C), meaning it will solidify under low-temperature storage conditions and requires heating to return to a liquid state.
5. Miscibility: Dimethyl Sulfoxide is completely miscible with water, alcohols, ethers, and many other organic solvents.
6. High Permeability: DMSO can penetrate skin and other biological membranes, making it versatile, but caution is needed as it may introduce dissolved toxins into the skin.
7. Low toxicity and environmental impact: DMSO is considered a "green" or safer solvent alternative with lower acute toxicity.

DMSO/Dimethyl Sulfoxide Uses
- Chemical Synthesis: DMSO is used as a reaction medium for resins and dyes, acrylic polymerization, and as a spinning solvent.
- Organic Solvent: It is an efficient solvent for organic synthesis, polymerization, and condensation reactions.
- Pharmaceuticals: Dimethyl Sulfoxide has anti-inflammatory and analgesic properties and acts as a penetration enhancer for drug delivery through the skin.
- Agriculture: Used as a pesticide additive to improve the efficacy of plant penetration.
- Industrial: Employed as a solvent for synthetic fibers, capacitor dielectric, brake oil, and rare metal extraction.
Safety information
To ensure the quality and safety of DMSO chemicals:
- Store in a cool, dry, well-ventilated place.
- Keep away from strong oxidizers.
- Use airtight containers to prevent moisture absorption.
- Avoid skin contact (the substance can be absorbed through the skin).
