A Blood Group H Type I trisaccharide ligand equipped with an amine-functionalized alkyl linker. The primary amine can be covalently coupled with N-hydroxysuccinimide (NHS) activated esters to form stable amide bonds, providing a straightforward route to conjugate the ligand onto NHS-activated molecules and surfaces. This compound presents the Blood Group H Type I trisaccharide (Fucα1-2Galβ1-3GlcNAc), a histo-blood group antigen and the precursor to Blood Group A and B Type I antigens. It is a ligand for fucose- and H-antigen-recognizing lectins and a probe for blood group and host-pathogen interaction studies.
