Compare YUJI industrial, pharmaceutical and electronic DMSO specifications and choose the parameters that matter to your application.
DMSO grade selection involves more than purity. Water, acidity, UV characteristics, conductivity and trace metals can affect how a solvent performs in a particular process. Grade names are supplier descriptions; they do not, by themselves, establish pharmacopeial compliance, GMP status or suitability for a finished drug or semiconductor process.

Compare the Listed YUJI Specifications
| Parameter | Industrial | Pharmaceutical | Electronic |
|---|---|---|---|
| DMSO content | ≥99.90% | ≥99.96% | ≥99.98% |
| Moisture | ≤1,000 ppm | ≤300 ppm | ≤300 ppm |
| Acid value | ≤0.03 mgKOH/g | ≤0.02 mgKOH/g | ≤0.01 mgKOH/g |
| Color (APHA) | ≤10 | ≤10 | ≤10 |
| Additional listed controls | See full specification | UV absorbance, UV ratios and non-volatile residue | Conductivity ≤0.30 µS/cm; listed metal ions ≤10 ppb |
The electronic grade metal specification covers Na, Mg, Al, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn and Pb. It should not be read as an unspecified total-metals limit. Review the complete parameter list and agreed testing methods.
Match the Grade to the Process
Industrial grade can be evaluated for chemical synthesis and industrial processing where its listed impurity limits meet the process requirements. Pharmaceutical grade adds UV and residue controls, but use in an API, excipient or other regulated application requires a separate qualification against the applicable requirements. Electronic grade adds conductivity and listed trace-metal controls relevant to contamination-sensitive processes.
Application labels are a starting point. A process involving a water-sensitive reagent may require a tighter moisture specification than any standard grade. An electronic process may impose additional ion or particle limits. Ask for a sample and a representative COA when evaluating a new source.
What to Check Before Ordering
Specify your target parameters, test methods, expected quantity, packaging and destination. Review the current specification and batch COA, and confirm any required documentation or certifications directly. YUJI matches these requirements to suitable manufacturing sources in China.
