Beyond gas-phase approximations

Why solution-phase predictions matter for real-world chemistry

Gas-phase only

  • Most predictions ignore solvent effects
  • pKa shifts not captured
  • Conformational changes in solution missed
  • Formulation failures discovered too late

FluxMateria Solvation

  • Explicit solvation free energy calculations
  • Solvent-dependent property predictions
  • pH and temperature effects modeled
  • Formulation-relevant screening from day one
