Disialyllacto-N-hexaose I

CAS: 137636-98-7

Disialyllacto-N-hexaose I is a complex carbohydrate that belongs to a class of saccharides called polysaccharides. Disialyllacto-N-hexaose I is synthesized through the methylation and glycosylation of sucrose. It has been modified by Click chemistry with a maleimide group to create an amide bond between the terminal alpha position on the glucose residue and the terminal alpha position on the N-acetylglucosamine residue. This modification can be used for Polysaccharide analysis, such as MALDI TOF MS. Disialyllacto-N-hexaose I has a CAS number of 137636-98-7 and has been shown to have high purity without any impurities or contaminants.
