N-azidoacetylglucosamine-tetraacylated (Ac4GlcNAz) is an unnatural azido-containing monosaccharide building block. The azide moiety can be used for modification though chemoselective ligation chemistries including CuAAC, Cu-free click reaction or Staudinger ligation. The acetyl groups increase solubility in many solvents and make handling of this reagent easier.
