Title:
NEW CRYSTAL FORM OF TRISACCHARIDE
Document Type and Number:
WIPO Patent Application WO/2023/221758
Kind Code:
A1
Abstract:
The present invention relates to a crystal of lacto-N-triaose, and belongs to the technical field of separation and purification. The technical solution of the present invention is a crystal form B of LNTII, which crystal form has characteristic diffraction peaks at positions of 2θ values (2θ±0.2°) of diffraction angles of 3.98, 6.98, 8.30, 9.60, 18.68, 19.25, 19.89 and 20.72 in the powder X-ray diffraction pattern. Provided in the present invention is a new crystal form of lacto-N-triaose, thereby achieving the iteration of a technique for preparing LNTII and providing a reliable technique for industrial large-scale production.
