Abstract
Disclosed are a crystal form of brexpiprazole and a preparation method therefor. The X-ray powder diffraction pattern, which is detected with Cu—Kα radiation, of the crystal form of brexpiprazole has characteristic peaks at the positions where 2θ is about 9.1±0.2, 15.2±0.2, 15.7±0.2, 17.6±0.2, 18.1±0.2, 24.4±0.2. The crystal form I of brexpiprazole has a high purity, good stability and good reproducibility, and is suitable for industrial production.
