An α-D-mannose ligand equipped with an azide-functionalized linker through a short ethyl spacer. The terminal azide can be covalently coupled to alkyne partners via copper-catalyzed azide-alkyne cycloaddition (CuAAC), or to dibenzocyclooctyne (DBCO) and related strained alkynes using copper-free click chemistry, forming stable 1,2,3-triazole linkages. This compound provides an α-D-mannose building block for glycoconjugate synthesis and the construction of probes for mannose-recognizing receptors and lectins, including the mannose receptor (CD206) and DC-SIGN, with relevance to immune targeting and pathogen-recognition research.
