1,3,4,6-Tetra-O-acetyl-N-azidoacetylgalactosamine is an azido-tagged analogue of N-acetylgalactosamine. It features azide functionality on the N-acyl side chain and is acetylated to aid in cell membrane permeation. It is metabolised by mammalian cells and incorporated into mucin-type-O-linked glycoproteins. The azide functionality is exploited as a biorthogonal functional group that can be reacted with phosphine probes by the Staudinger ligation.

Ac4GalNAz is a synthetic sugar analogue that can be used in the study of glycobiology. Glycobiology is the study of the structure and function of carbohydrates (glycans) in biological systems.
