BIOVIA COSMOtherm (COSMO-RS) review
A specialized COSMO-RS tool for predicting molecular properties in pure and mixed liquids.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
BIOVIA COSMOtherm applies COSMO-RS to predict thermodynamic properties of molecules in pure and mixed liquids. Its intended audience includes researchers and teams in chemistry, chemical engineering, formulation, drug development, environmental science and materials research. The work centers on molecular thermodynamics rather than broad process simulation, making it most relevant when questions concern how compounds behave in mixtures. It is a focused fit for mid-market and enterprise organizations seeking these predictions, rather than a general chemical operations system.
Its feature set spans solubility prediction for liquids, solids and gases, activity coefficients, partitioning, and liquid-liquid, liquid-vapor and liquid-solid phase equilibria. It also calculates vapor pressure, free energy of solvation, Henry’s law predictions, pKa and solvent-dependent reaction equilibria. Conformer populations in mixtures and micelle and membrane partitioning extend the scope to additional molecular contexts. A graphical user interface supports interactive work, while command-line batch processing offers another route for repeatable or workflow-oriented calculations. This breadth within thermodynamic prediction is the product’s central strength; buyers looking for inventory, safety-data-sheet management, formulation management or regulatory compliance should look elsewhere.
COSMOtherm is a Windows desktop product deployed on-premises, so teams should account for that environment when assessing fit. The published pricing model is contact sales, and there is no free plan. Support channels include documentation and community resources. Researchers whose main need is COSMO-RS-based prediction of solubility, partitioning, phase behavior or related molecular properties may find its concentrated scope appropriate. Teams that need a broader process simulator, mobile access, or a different deployment platform should compare alternatives before choosing it.
BIOVIA COSMOtherm (COSMO-RS) pros and cons
- Where it wins
- Predicts solubility across liquids, solids and gases
- Covers phase equilibria, partitioning, vapor pressure and pKa
- Offers graphical workflows and command-line batch processing
- Where it doesn't
- Windows desktop deployment limits platform flexibility
- Contact-sales pricing makes cost assessment less direct
- Specialized thermodynamics scope is narrower than process simulation
