LogD, also known as the distribution coefficient, is the ratio of the total concentration of all compound forms, including ionized and un-ionized, in both aqueous and non-aqueous phases. The resulting value is affected by the pH of the aqueous phase, and for non-ionizable substances, logD is equal to log P regardless of pH. In order to measure distribution coefficients, the pH of the aqueous phase is maintained at a constant level to avoid any significant changes caused by the addition of the compound. To compute the negative logD value, the sum of the measured concentrations of the solute's forms in one solvent is divided by the sum of such concentrations in the other solvent first, and then the logarithm of this ratio is determined.What is the logD of this molecule in its negative form?
