PE634000: α-Man-PEG3-Azide label-new Fmoc-Ser(β-D-GlcNAc(Ac)3-(1-3)-α-D-GalNAc(Ac)2)-OHC12H23N3O8 337. 33 An D mannose ligand equipped with an azide handle through a hydrophilic PEG3 spacer. The terminal azide couples to alkynes via copper catalyzed azide alkyne cycloaddition (CuAAC) or to DBCO and related strained alkynes via copper free click chemistry, forming stable 1,2,3 triazole linkages. This compound provides an D mannose building block for glycoconjugate synthesis and the construction of probes for mannose recognizing receptors
