Description
Cyanomethyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside can be modified via treatment with sodium methoxide or HCl such that the nitrile of the cyanomethyl group is converted to a methyl imidate group. Cyanomethyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside can then be used to form glycoproteins
