QSAR models
List of QSAR models available for the prediction of physico-chemical, (eco) toxicological parameters, etc.
Collaborative projects
We participate in projects on REACH, biocides, nanomaterials, endocrine disruptors, etc.
Normative ICH
What characteristics should a QSAR model have from a regulatory point of view? A case of the ICH regulation. As we saw in our previous post about what QSAR models are and how are they created, the REACH (chemical products) and ICH (drug) legislations not only accept, but also promote the use of alternative methods […]

Statistical techniques
What statistical techniques do QSAR models use? As we have seen in the previous entries, QSAR models allow predicting properties or activities of molecules, and are obtained from the analysis of molecular descriptors with statistical and/ or machine learning techniques. QSAR models can be used qualitatively to classify a substance, for example as a skin […]

Molecular descriptors
What are molecular descriptors? In order to generate QSAR models, it is necessary to codify in some way the characteristics of the molecules, in order to have the most detailed possible description of these. In other words, it is necessary to translate the molecular structures into numerical values that can be easily understood by computer […]
