What is dimethyl sulfoxide?
Dimethyl sulfoxide, or DMSO, is a clear polar aprotic solvent known for its strong solvency and ability to dissolve many organic and inorganic compounds. It is used in pharmaceuticals, research, polymers, electronics, and specialty chemical processes.
DMSO sourcing is highly specification-driven. Buyers should compare purity, water content, color, acidity, residue, crystallization point where relevant, packaging, and batch documentation. Sensitive applications require stronger traceability.
Chemical Dekho indexes DMSO under CAS 67-68-5 so buyers can keep identity clear and compare offers by grade, purity, and documentation instead of only by price.

Purity control
Applications
Where dimethyl sulfoxide is used
DMSO is selected when strong polar solvency and process compatibility are required.
Pharmaceutical and synthesis workflows
Used as a process solvent, reaction medium, or specialty solvent where high purity and documentation matter.
Laboratory and research
Used in sample preparation, reagent handling, biological research contexts, and analytical workflows where appropriate.
Polymer and specialty chemicals
Used in polymer processing, resin systems, and specialty chemical manufacturing requiring strong polar solvency.
Electronics and high-spec uses
Used in selected electronics or precision workflows where impurity control and documentation are important.
Grade Selection
How to choose the right DMSO grade
DMSO buyers should start with intended application and required purity. Industrial grade may be sufficient for some processes, while pharma, laboratory, electronics, and sensitive specialty uses can require tighter impurity and moisture limits.
Ask suppliers for COA, SDS, TDS, packaging details, and batch traceability. Since DMSO is often used in sensitive workflows, documentation quality can be as important as headline purity.

Specification Snapshot
Dimethyl Sulfoxide specifications buyers usually compare
DMSO is usually bought for performance-sensitive applications, so buyers should align purity, water content, packaging, and documentation before comparing quotes.
Safety basics: DMSO requires careful skin exposure control.
This blog is a buyer guide, not a replacement for your SDS, site EHS procedure, or local compliance requirements.
DMSO can carry dissolved substances through skin more readily than many common solvents. Users should follow SDS guidance, avoid skin contact, use suitable gloves and eye protection, and prevent contamination.
