  • SPECIFICALLY-SHAPED CRYSTAL OF COMPOUND AND METHOD FOR PRODUCING SAME
    Publication number: 20210391038
    Abstract: The present invention provides a method for obtaining a specifically-shaped crystal (specifically, spherocrystal) of a compound with good reproducibility. This method for producing a specifically-shaped crystal (specifically spherocrystal) of a compound comprises: (1) a step for preparing a supersaturated solution of a compound having a degree of supersaturation equal to or higher than a critical degree of supersaturation; and (2) a step for precipitating a specifically-shaped crystal (specifically spherocrystal) of a compound from the supersaturated solution.
    Type: Application
