PE431000: β-Gal-PEG3-Alkyne label-new Viosterol-d3C15H26O9 350. 36 A D galactose ligand equipped with a terminal alkyne through a hydrophilic PEG3 spacer. The alkyne couples to azide functionalized partners via copper catalyzed azide alkyne cycloaddition (CuAAC), forming stable 1,2,3 triazole linkages. This compound provides a anomeric galactose building block for glycoconjugate synthesis, glycomimetic research, and the construction of probes for galactose recognizing proteins, including galectins
