Abstract:
1. A crystalline form of 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-[(trifluoro-methyl)sulfinyl]-1H-pyrazole-3-carbonitrile which is polymorph Form II exhibiting at least one of the following properties: (a) an X-ray powder diffraction pattern having characteristic peaks expressed in degrees 2° θ (+/−0.20° θ) at about 14.4, 15.7, 16.75, 17.2, 19, 20.7, 22.95, 23.55, and 32.15; (b) an infrared (IR) spectrum at the 3000 cm (c) a Differential Scanning calorimeter (DSC) thermogram having a single predominant endotherm at about 195° C. as measured by a Differential Scanning calorimeter (DSC) at a scan rate of 2° C. and/or 10° C. per minute.
