Comparison of ACD/LogP Freeware & Commercial ACD/LogP DB

Commercial Freeware
  • Obtain calculated logP values for up to 999 structures at a time
  • Check and choose tautomeric forms

Added features of ACD/LogP DB

  • Calculate an array of liquid properties (including PSA, #FRB, BCF, Koc, and Rule-of-5 properties)
  • View the calculation protocol for each individual prediction
  • Search the internal database for literature references by substructure, IUPAC name, logP value, etc.
  • Build your own databases of logP values
  • Import and process SDfiles
  • Access to scripting tools for calculation of related parameters
  • Improve accuracy of prediction with your own experimental data using our training tools—System Training and Accuracy Extender
  • Obtain calculated logP values for individual structures in ChemSketch using the version 10 model
  • Check and choose tautomeric forms

Note: If you are working with ionizable compounds, remember that logP is only relevant for the neutral substance. To take ionization into account you must use the pH-dependant hydrophobicity descriptor, logD
