PE434000: β-Gal-PEG3-Azide Pack Size:100 mg (S)-N-(2-(1-(3-Ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethyl)-1C12H23N3O8 337. 33 A D galactose 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 a anomeric galactose building block for glycoconjugate synthesis, glycomimetic research, and the construction of probes
