Specific Solubility Models

CDK-Based Models

CDK001 Modeling the solubility of organic compounds in 1-octanol

Abraham General Solvation Model

The Abraham general solvation model can be used to predict the solubility of organic compounds in organic solvents via the linear free energy relationship (LFER):

Log S = Log S_aqueous + c + e * E + s * S + a * A + b * B + v * V

where c, e, s, a, b, v are the standard Abraham solvent coefficients and E, S, A, B, V are the solute descriptors. In certain circumstances it is advantageous to use the LFER:

Log S = Log S_aqueous + e_0 * E + s_0 * S + a_0 * A + b_0 * B + v_0 * V

where e_0, s_0, a_0, b_0, v_0 are the (c=0) - regressed solvent coefficients.
