Title:
NEW CRYSTAL FORM OF TRISACCHARIDE
Document Type and Number:
WIPO Patent Application WO/2023/216890
Kind Code:
A1
Abstract:
The invention provides a lacto-N-triose II crystal form A and a preparation method therefor. The powder X-ray diffraction pattern of the crystal form has characteristic diffraction peaks at diffraction angles (2θ ± 0.2°) of 4.80, 8.32, 9.62, 12.72, 18.67, 19.90, 21.05, and 21.59 degrees. The lacto-N-triose II crystal form A provided by the invention has good moisture absorption resistance and stability, can reduce packaging costs, and prolongs product shelf life.
