The present disclosure relates generally to crystalline forms of anhydrous D-glucitol, 1-deoxy-1-(methylamino)-, 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1, 4-dihydro-7 -(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboyxlate, compositions comprising the same, and methods of making the same. Delafloxacin is an fluoroquinolone antibiotic with the chemical structure and the chemical name 1-deoxy-1-(methylamino)-, 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihy dro-7 -(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboyxlate. Studies have indicated the existence of three anhydrous polymorphs of delafloxacin, as well as a trihydrate and methanol and ethanol solvates. |
