Drug solubility is one of the most significant physicochemical properties as it related to drug design, formulation, quantification, recrystallization, and other processes, so understanding crucial for pharmaceutical industry. In this context, research presents thermodynamic analysis sulfadiazine (SD) in cosolvent mixtures {acetonitrile + 1-propanol} at 9 temperatures (278.15 K–318.15 K), which...
