Application

Uses: This product is an important derivant of D-glucopyranose, it is used for pharmaceutical intermediates and used in biochemical reactions and other chemical reactions.

As a pharmaceutical intermediate, for example, used in synthetize derivants of 3-position glycosylation for anti-Alzheimer disease, synthetize carbohydrate complexes of sulfate/ phosphate and glycoside derivatives of indolopyrrolocarbazole for treatment cancer, synthetize compounds of perfluoroalkyl-containing sugar radicals for diagnosis of cancer, synthetize Voglibose, ertugliflozin, nojirimycin and its derivants, glucose ester of glycyl-propionic acids for cure diabetes, and synthetize other pharmaceuticals such as polysaccharide, glycosylations derivatives with benzotriazole/ nitrophenyl and phospholipid-saccharide conjugates for treatment sepsis, meningitis, AIDS, osteoporosis, osteitis deformans or Paget’s diease etc. 

Used in prepare 1-halogenation glucopyranose and synthesis other derivatives of 1- C-alkyl or glycosides -α-d-glucopyranosides, and so on. Moreover, the compound of 2,3,4,6-tetra-O-benzyl-1-C-vinyl-α-D-glucopyranose conjugate with 15-crown-5 ether is a novel chiral phase-transfer catalysts.

Storage: Maintain in cool, dry container.
