The N-pyridine pKa value was determined from its pH-solubility profile, which was in accordance with that of the experimental value of methyl isonicotinate. Also, the ethanol cosolvency in ethanol:water mixtures at 25°C was studied, and log-linear and nonlinear solubilization models were applied to the experimental solubility AZT-Iso data, which allowed us to predict its solubility in those solvent mixtures at a determined content of cosolvent.", pages = "191-202(12)", url = "http://www.ingentaconnect.com/content/tandf/lncn/2006/00000025/00000002/art00005" doi = "doi:10.1080/15257770500446964" }
