An α-D-N-acetyllactosamine (LacNAc) ligand equipped with an amine-functionalized linker through a short propyl spacer. 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 provides an N-acetyllactosamine (LacNAc; Galβ1-4GlcNAc) building block presented on an α-linked aglycone, a core disaccharide of N- and O-glycans and a ligand for galectins. It is a substrate for sialyltransferases and fucosyltransferases.
