1) A range of products with the GREEN LABEL specially prepared for analytical controls.
They are easy to find in the alphabetical list through their code ending with the letter "S". This letter "S" provides an insurance that specific care has been taken in the course of their production in such a way as to guarantee a similar analytical response between one batch and another.
They are delivered with their chromatographic condition of use.

In order to help you establish your analysis files, we propose a range of GREEN LABEL products where the article code from the 9000 series does not include the "S" letter. These products are delivered, for each batch supplied, with complementary structural elements - infrared, mass, nuclear magnetic resonance and ultraviolet spectrum …

2) A range of products with the RED LABEL for R&D.
These are technical products for numerous applications: hemisynthesis, biochemistry, toxicological studies and objectivation studies, etc…
In no case, can these products be used for purposes of quantitative analysis without complementary analyses by yourselves.
Far higher quantities than those mentioned in the catalogue can be supplied not only for the high-purity products but for technical products.

We would draw your attention to the fact that, we have not made physiological activity or toxicity tests for any of our products.
The range proposed in this catalogue has been designed for laboratory use for analytical or research purposes.
