Amsterdam Modeling Suite


Instantaneous thermodynamic property prediction

A database of over 2500 compounds containing solvents & small molecules (list) and ionic liquids (list, tutorial ionic liquids) facilitates instantaneous predictions of log P, solubilities, and other properties. It is easy to add new molecules to the database using a dedicated ADF template or ad-hoc estimation directly from SMILES strings.

Step-by-step Tutorials show how to set up COSMO-RS property calculations with the GUI and our Scripting tools enable rapid solvent screening.

Solvent optimization
Scm cosmo rs@2x

Chemical engineers may want to optimize distillation processes by tweaking vapor pressures and boiling points, while medicinal chemists perhaps want to maximize solvent extraction efficiency to separate the active pharmaceutical ingredient from its main contaminant, or maximize solubility with excipients.

Our solvent system optimization tool is perfectly placed to help reduce the experimental search space by optimizing solvent mixtures for solubility or liquid-liquid extraction across a set of selected solvents.

Applications for scripting with COSMO-RS/SAC include optimizing catalysts, solubility parameters, pKa values and sorption in ionic liquids.

Conformers, aggregates, protonation states

Since AMS2020, you can deal with more complex solution behavior where compounds may behave differently in various solvents or under different conditions. These include cases where the solute dissociates, aggregates, or has multiple conformers (seeTutorial).


COSMO-RS and COSMO-SAC predict thermodynamic properties and descriptors for polymers such as activity coefficients, vapor pressures, partition coefficients, solubilities, and Flory-Huggins Chi. In combination with the new polymer builder of the graphical user interface, these new features significantly extend our polymer tools since AMS2019.
