The log D coefficient, also known as the distribution coefficient, is a metric used to measure the ratio of all compound forms (including ionized and un-ionized) present in each of the two phases - one of them primarily being aqueous. This ratio is largely affected by the pH level of the aqueous phase. However, non-ionizable compounds at any pH follow a constant log P. To determine the distribution coefficients accurately, the pH level of the aqueous phase needs to be buffered to a specific level to avoid any significant fluctuations resulting from compound introduction. Each negative log D value is then ascertained by taking the logarithm of the ratio - constituting the summation of concentrations of solute's multiple forms in one solvent and comparing it to the summation of concentrations of its forms in the other solvent.Could you please tell me the value of the negative logarithm of the dissociation constant of this particular molecule?
