Solvent screening is of great importance in the design and optimization of drug crystallization. In this paper, the solubility data of cefazolin acid in five pure solvents and one binary solvent mixtures (N, Ndimethylformamide + 2-propanol) were experimentally measured in temperature range from (278.15 308.15)K by using UV spectrometer method. The melting temperature of cefazolin acidwas estimated by three-level group contribution method. All the experimental solubility data were correlated by the modified Apelblat model and the lh equation. The experimental solubility data in binary solvent mixtures were also correlated by the nearly ideal binary solvent CNIBS/Redlich Kister model. In addition, based on the modified van t Hoff equation, the thermodynamic properties of cefazolin acid dissolution process were also calculated and discussed.
