Application

Azidoacetic acid NHS ester is a simple azido-containing reagent with an N-hydroxysuccinimide (NHS) ester that can be reacted with primary amines at pH 7-9 forming a stable amide bond. The azide allows for chemoselective ligation with an alkyne or cyclooctyne. It is generally used to functionalize amines and amino acids with azidoacetyl groups. It is generally used in click chemistry applications.
