Provided is a process for hydrating cyclophosphamide freeze-dried compositions and products obtained therefrom, including injectable compositions. The cyclophosphamide compositions provided may contain relatively small amounts of impurity A and impurity B. In some embodiments of the invention, the composition may be characterized by a powder x-ray diffraction pattern having peaks at 20.4, 23.6, 23.7, and 25.2 degrees two theta ± 0.2 degrees two theta |
