Azidoacetic Acid NHS Ester

An amine-reactive building block used to derivatize primary amines with an azido group.


  • Solubility – reagent easily dissolves in water-miscible solvents for subsequent dilution into aqueous reaction mixtures
  • Reactivity – NHS Esters are specific for covalent attachment to primary amines (a side chain of lysine or N-terminus of polypeptides)
  • Short spacer – a 2 carbon atom spacer arm keeps azide group close to tagged molecules

Azidoacetic Acid NHS Ester is a simple azido-containing reagent that reacts with primary amines at pH 7-9 forming a stable amide bond. A short spacer arm adds minimal mass to modified molecules (84.1 daltons).
