degrees of purity like "technical", "pure", "puriss" or "Ph. Eur." play a decisive role in the assessment of chemicals.
👉 In this article you will learn:
- what the individual degrees of purity mean
- how they differ
- What you should look out for when choosing
👉 Basics of CDS: What is CDS (chlorine dioxide solution)?
Why are degrees of purity important?
The purity of a chemical influences its composition and possible secondary constituents.
Depending on the application, this can be crucial - especially for precise or analytical requirements.
Important: The manufacturer's specific specifications are always decisive.
The most important degrees of purity at a glance
Technical
- Large-scale production
- Possible contamination
- Deviations in color or odor
- Suitable for technical applications
Pure (purum)
- Minimum content mostly ≥ 97 %
- Significantly lower impurities
- Suitable for laboratory and synthesis
Cleanest
- Very high purity
- Foreign substances hardly detectable
- Suitable for analytical applications
Ph. Eur.
- Standard of the European Pharmacopoeia
- Very strict quality requirements
- for pharmaceutical applications
Important note on comparability
Designations such as "pure" or "puriss" are not fully standardized.
- Manufacturers define the exact quality
- Products can differ
- Technical data sheets are crucial
Food quality vs. chemical purity
Food quality is often perceived as particularly pure - but this is not always correct.
- "Purest" and "Ph. Eur." are often more strictly defined
- Food quality allows certain tolerances
What does this mean for CDS?
With CDS the quality of the raw materials and the manufacturing process play a central role.

👉 Understanding differences: CDS vs. MMS - difference simply explained
Differences are particularly evident in:
- Purity
- By-products
- Stability
Conclusion
- Technical → Simple applications
- Pure → Standard laboratory
- Cleanest → Analytical precision
- Ph. Eur. → Highest pharmaceutical requirements
The right choice always depends on the intended use.
