Please could you let me know which algorithm the ChemAxon LogP calculator uses?
Our molecular modeler prefers CLogP. However I know that there are other algorithms such as ALogP, MLogP, XLogP etc.
Many thanks.

Hi,
I have moved your question to the appropriate section of the forum.
My colleagues will answer your question shortly.
Best regards,

Hi,
Our logP calculator based on this method:
Viswanadhan, V. N.; Ghose, A. K.; Revankar, G. R. and Robins, R. K., J.Chem.Inf.Comput.Sci., 1989, 29, 3, 163-172
We supplemented the original atomic fragments with new ionic and neutral atom types.
We pay special attention on the logP calculation of zwitterions. For zwitterionic molecules we calculate the distribution coefficient (logD) of the submitted molecule at the isoelectric point.
