Abstract:
1. A crystalline Vemurafenib choline salt designated as Form C1 and characterized by a powder XRD pattern with peaks at 7.9, 12.4, 13.8, 19.2 and 20.6 degrees 2-theta±0.2 degrees 2 theta and one or more of the following; a powder XRD pattern as shown in a solid state 13C NMR spectrum having chemical shift differences between said characteristic peaks and a peak at 149.5 ppm±0.2 ppm of −13.2, −30.1, −33.2, −93.3 and −95.9 ppm±0.1 ppm, respectively; a solid state 13C NMR spectrum substantially as shown in and combinations of these data.
