Abstract:
1. Type II crystal of L-alpha-glyceryl phosphoryl choline, wherein an onset temperature is 62° C. and an absorption peak is 66° C., and an onset temperature is 141° C. and an absorption peak is 145° C., respectively, in a differential scanning calorimetry (DSC) analysis, wherein 2θ-diffraction angles of the diffraction pattern are 10.3±0.2°, 12.2±0.2°, 13.4±0.2°, 14.8±0.2°, and 20.6±0.2° in an X-ray diffraction (XRD) analysis, and wherein the Type II crystal of L-alpha-glyceryl phosphoryl choline, as a mono-hydrate, has a polyhedral structure of a hexagonal system.
