Abstract:
1. A crystalline form of carvedilol dihydrogen phosphate characterized by data selected from the group consisting of: (a) X-ray powder diffraction reflections at about: 7.6, 9.8, 10.9, 21.2 and 25.0 degrees two theta±0.2 degrees two theta; (b) any five peaks selected from the following list of PXRD peaks at about: 7.6, 8.5, 9.8, 10.9, 12.0, 13.3, 15.2 and 16.9±0.2 degrees two theta; (c) X-ray powder diffraction reflections at about: 7.6, 10.9, 13.3, 15.2 and 18.8 degrees two theta±0.2 degrees two theta; d) X-ray powder diffraction reflections at about: 7.6, 8.5, 9.8, 15.2 and 16.9±0.2 degrees two theta; (e) X-ray powder diffraction reflections at about: 7.6, 9.8, 10.9, 14.7, 15.2 and 22.8±0.2 degrees two theta; (f) X-ray powder diffraction reflections at about: 7.6, 8.5, 9.8, 13.3 and 15.2±0.2 degrees two theta; and (g) an X-ray powder diffraction pattern substantially as depicted in
