  A cocrystal containing the 1′R-diastereomer and the 1'S-diastereomer of sofpironium bromide at a ratio of 1:3 (Form CO), a crystal mixture (for example, Form B) containing Form CO and a crystalline form of the 1′R-diastereomer (Form MN), and a method for preparing sofpironium bromide, which is suitable for manufacture of the crystal mixture are provided. Form CO and a crystalline form of sofpironium bromide containing Form CO (for example, Form B) have superior stability without hygroscopic property, and accordingly they can be preferably used as a raw material of medicaments.
