Brief introduction to pKa prediction platform


Heterolytic bond dissociation energies (pKa) are one of the most important properties for organic molecules, which play very import rules in chemistry, biology, medicine, and geology. We provided a fast pKa prediction platform free of charge herein, which was based on two different machine learning methods. The pKa training set included more than 19,000 experimental data published so far. We thank iBonD and Dr. Jindong Yang for his comments and suggestions.


The pKa prediction platform are only free of charge for non-profit making academic use.
