Characterization of Polymorphs of a Novel Quinolinone Derivative, TA-270 (4-Hydroxy-1-methyl-3-octyloxy-7-sinapinoylamino-2(1H)-quinolinone)

The polymorphic forms and amorphous form of TA-270 (4-hydroxy-1-methyl-3-octyloxy-7-sinapinoylamino-2(1H)-quinolinone), a newly developed antiallergenic compound, were characterized by powder X-ray diffractometry, thermal analysis, infrared spectroscopy and solid state 13C-NMR. The intrinsic dissolu...
