Oxiracetam compound adopting crystallization form and preparation method thereof

The invention relates to an oxiracetam compound adopting a crystallization form and a preparation method thereof, and belongs to the technical field of medicines. In an X-ray powder diffraction pattern of the oxiracetam compound, characteristic peaks are achieved when the angle 2 theta is within the ranges of 5-5.4 degrees, 11.3-11.7 degrees, 13.4-13.8 degrees, 15.6-16.0 degrees, 17.3-17.7 degrees, 18.9-19.3 degrees and 20.6-21.0 degrees respectively. The oxiracetam compound adopting the crystallization form has high bioavailability and high stability, has good characteristics that related substances are not increased and the clarity is not reduced when the oxiracetam compound is placed for a long term, and is more suitable for being used as a crude drug to be used for producing and storing a medicinal preparation.
