Testimonials

"I find almost daily confirmation that helping research, development and production people to understand solubility issues can transform their ability to develop new products and solve real-world problems.

Hansen Solubility Parameters are excellent for providing general insights into solubility, but for those who need a deeper understanding or more powerful predictions, I recommend the tools from COSMOlogic, which are based on a more powerful thermodynamic and quantum mechanical approach, known as COSMO-RS."

Professor Steven Abbott
TCNF, coauthor of the HSPiP package that implements practical solubility thinking based on Hansen Solubility Parameters

"With the help of COSMOtherm we succeeded in finding a replacement solvent in a chemical process, which now saves about 1 Mio. EUROs per year in a plant."

"From my own experience and from the feedback of colleagues I know that people like COSMOtherm very much. I personally even tend to trust COSMOtherm results more than experimental data in many situations. Your COSMOtherm is an excellent tool. Congratulations!"

"Morphochem uses the COSMOsim for both evolutionary ligand based target focused library design and MedChem lead optimization. The usefulness and reliability of COSMOsim has been proven in a variety of in-house projects and external collaborations. Morphochem uses furthermore COSMOsim and COSMOtherm in combination for the multiparametric optimization of pharmacologically relevant physico-chemical molecular properties like aqueous solubility and various partition coefficients."

"Let me tell you that your method COSMO-RS is very useful in our practical industrial researches and developments. My colleagues and myself are always using it for industrial problems with surprise to the quality of COSMO-RS !

As a quantum chemist, not only from the practical point of view, but also from a healthiness of the theory, I trust only a few methods for solvation problems. For our industrial problems, your COSMO-RS is the best method among available tools."

Dr. Shin Nakamura

"The COSMO-RS method provides a very efficient approach to thermodynamic data of liquid mixtures. Especially its universal applicability to almost the entire molecular chemistry makes it to an important research tool. In BASF the potential of this method was recognized very early, and as a consequence we have supported the implementation of COSMO in the highly efficient quantum chemistry program TURBOMOLE.

Meanwhile COSMO and COSMO-RS are routinely used in molecular modeling and they are applied to many areas of research and process development."

Dr. Ansgar Schäfer
BASF Computational Chemistry

"COSMO-RS yields reliable predictions for the partition coefficients in liquid-liquid systems and can compete with group contribution methods in this field of application. Because of its sound physical basis and in contrast to group contribution methods COSMO-RS gives a deeper insight into the thermodynamic properties and allows a rough estimation of mixture properties based on the pure components σ-profiles. This distinctive feature allows it to be used for the systematic selection of solvents in process technology, or even for their design."

"We are using the COSMOquick software meanwhile as a routine procedure to quickly screen solvents for solubility experiments and to pre-screen potential cofomers for cocystal screening. "

"We used the computational software COSMOtherm. The choice of COSMOtherm among a plethora of free and commercial computational tools available today for logP/logD calculations was justified by two reasons: (1) unlike most logP calculators, it uses the three-dimensional structure of the molecules, and (2) COSMOtherm allows calculation of logP values in non-octanol/water systems. Furthermore, COSMOtherm is the only commercial a priori (not restricted by the availability of experimental data) method available today."

Chapter 10.3.3.3: "A major benefit of the COSMO-RS thermodynamic model over GCMs is its consideration of longer range molecular interactions such as hydrogen bonding. One of the main advantages of COSMO-RS is that it can be used to predict phase equilibria in systems where the UNIFAC interaction parameters are not available."

"Within the last years the Conductor like Screening Model for Real Solvents (COSMO-RS) has been established to predict complex properties of liquid systems. In this process, data from quantum chemical calculations are fed into the thermodynamic model. While only few empirical parameters are required due to the use of quantum chemical information, the method still allows for predictions for unusual substances. Klamt et al. demonstrated the power of their approach in a blind test for the prediction of Cyclohexane/Water distribution coefficients: their contribution delivered the most accurate distribution coefficients of the submitted 76 methods and the overall best results for the 53 tested substances."
