Abstract
Disclosed in the present invention are a crystalline form B of a tetrahydrothienopyridine compound having a structure as represented by Compound I, a preparation method, a composition and an application thereof, for use in solving the problems in the prior art of lots of impurities, low content, bad crystalline form stability, and inability to form a drug. The crystalline form B uses Cu-Kα radiation, and X-ray powder diffraction expressed at a 2θ angle has characteristic peaks at 11.21±0.2°, 12.61±0.2°, 14.69±0.2°, 16.14±0.2°, 17.81±0.2°, 20.22±0.2°, and 22.10±0.2°. The crystalline form B of the present invention has few of impurities, good stability, good crystallinity, and reproducibility, and is suitable for industrial production. Moreover, the crystalline form B has an unexpectedly stronger anti-ADP-induced platelet aggregation effect and better fluidity.
