Products Description
Dimethyl Sulfoxide (DMSO) is an organosulfur compound with the chemical formula (CH₃)₂SO. It is a colorless, highly polar aprotic liquid that is miscible with both water and most organic solvents, making it one of the most versatile industrial and laboratory solvents available.
Uses of DMSO
1. Chemical and Organic Manufacturing
- Used in Swern oxidation and other reactions requiring a high-boiling, inert polar solvent
- Effective solvent for both polar and nonpolar compounds in organic synthesis
2. Biochemistry and Pharmaceutical Industry
- Used as a cryoprotectant (~10%) in cell freezing media to prevent ice-crystal damage during storage
- Used as a penetration enhancer in transdermal drug delivery formulations
- FDA-approved for bladder instillation in the treatment of interstitial cystitis, under physician supervision
3. Industrial Usage
- Solvent for paints, coatings, and industrial cleaning agents
- Degreasing and paint-stripping formulations

FAQ
Q: Is there a discount?
Yes, we will offer a better price if the quantity is larger.
Q: What is the minimum order quantity?
The minimum order quantity depends on packaging format.
For DMSO, the minimum order quantity is typically 1 drum (200–250 kg). Smaller sample quantities may be available for quality testing - please contact us to discuss.
Q: What is the port of loading?
Shanghai, Tianjin, Qingdao, etc.
Q: What is the mode of transportation?
For small orders, we will send the goods by international express such as FEDEX, which takes 3-7 working days. Other transportation methods can be negotiated. For large orders, we will ship the goods by sea, which takes one month. If the situation is urgent, you can choose air transportation.
Q: Is DMSO classified as a hazardous/dangerous good for shipping?
DMSO is not classified as Dangerous Goods by IATA, IMDG, US DOT, or ADR - its flash point (≈87–89°C) is above the 60°C threshold that would trigger UN Class 3 flammable-liquid regulation. This means DMSO generally ships under standard cargo documentation for both air and sea freight, without special DG labeling or handling fees. We provide full COA/TDS/SDS documentation with each shipment to support your import compliance.
