2-[(Azidoacety)amino]-2-deoxy-D-mannose,

2-[(疊氮乙酰)氨基]-2-脫氧-D-甘露糖，

N-Azidoacetylmannosamine, also called ManNAz and 2-[(2-azidoacetyl)amino]-2-deoxy-D-mannose, is a click reagent for metabolic labelling of ManNAc. The azide is able to react with an alkyne in a 1,3-dipolar cycloaddition reaction (click chemistry) to enable linking to a fluorescent probe or a biotin. N-Azidoacetylmannosamine has been used in the chemical modification of glycoproteins to improve their in vivo efficacy and to label them for detection.
