Summary:Crystal form of besipirdine chlorhydrate (Form I) corresponding to the Formula (A) below: the aforementioned form being characterized at least by one of the following physico-chemical properties: a) In FTIR, it displays at least the following absorption bands of the infrared spectrum: 778, 1198, 1121, but not the following absorption bands of the infrared spectrum: 3395, 1583, 732, the aforementioned bands being expressed in cm-1 at ±5 cm-1; b) In PXRD, it shows at least the following reflections, which are the most intense ones but whose intensity hereafter is given for information only: Formula (II) c) In DSC, it displays at least an endothermic peak at 187.3±2.0° C. using 5° C./min scanning conditions, and a fusion enthalpy DeltaH of 130.4±2.0 J/g. The invention also relates to the processes used for the preparation of form I as well as its applications in urology.
