Heparin disaccharide III-S trisodium salt 

2-Deoxy-4-O-(4-deoxy-2-O-sulfo-α-L-threo-hex-4-enopyranuronosyl)-2-(sulfoamino)-D-glucose sodium (1:3)

Heparin disaccharide III-S trisodium salt is a synthetic and custom-synthesized drug with high purity. It is a complex carbohydrate with a molecular weight of 597.1 g/mol, an Oligosaccharide with a molecular weight of 1,008.3 g/mol, and a Glycosylation with a molecular weight of 1,069.4 g/mol. Heparin disaccharide III-S trisodium salt has been modified by the addition of fluorine atoms to create an active form that is highly reactive to electrophilic groups on proteins or nucleic acids. It can be used for Click modification or methylation reactions to modify proteins or DNA molecules in order to study protein-protein interactions or protein conformational changes in response to external stimuli.
