  • Crystalline forms of ibandronic acid and processes for the preparation thereof
    Publication number: 20090099390
    Abstract: A crystalline ibandronic acid characterized by data selected from the group consisting of at least one of a powder x-ray diffraction pattern having peaks at about 4.1, 12.3 and 13.4±0.2 degrees two-theta and at least two more peaks selected from the group consisting of: 8.2, 11.3, 16.2 and 16.9 and 20.8±0.2 degrees two-theta, and by a powder X-ray diffraction pattern depicted in FIG. 1 is provided. Also provided is a crystalline ibandronic acid characterized by data selected from the group consisting of at least one of a powder x-ray diffraction pattern having peaks at about peaks at about 5.2, 11.7, and 18.7±0.2 degrees two-theta and at least two more peaks selected from the group consisting of: 5.8, 10.1, 12.0, 17.1, and 20.0±0.2 degrees two-theta and a powder X-ray diffraction pattern as depicted in FIG. 2. Methods of preparing the crystalline forms are also provided.
