Solubility and Thermodynamic Data of Febuxostat in Various Mono Solvents at Different Temperatures.

ABSTRACT: This study examines the solubility and thermodynamics of febuxostat (FBX) in a variety of mono solvents, including "water, methanol (MeOH), ethanol (EtOH), isopropanol (IPA), 1-butanol (1-BuOH), 2-butanol (2-BuOH), ethylene glycol (EG), propylene glycol (PG), polyethylene glycol-400 (PEG-400), ethyl acetate (EA), Transcutol-HP (THP), and dimethyl sulfoxide (DMSO)" at 298.2-318.2 K and 101.1 kPa. The solubility of FBX was determined using a shake flask method and correlated with "van't Hoff, Buchowski-Ksiazczak λh, and Apelblat models". The overall error values for van't Hoff, Buchowski-Ksiazczak λh, and Apelblat models was recorded to be 1.60, 2.86, and 1.14%, respectively. The maximum mole fraction solubility of FBX was 3.06 × 10^-2 in PEG-400 at 318.2 K, however t
