Properties

Description

Azido-PEG1-CH₂CO₂-NHS acts as a PEG linker containing both azide and NHS ester functionalities. The hydrophilic PEG spacer improves water solubility in aqueous solutions. The azide group can engage in reactions with alkynes, BCN, and DBCO via click chemistry methods to yield stable triazole linkages. Moreover, the NHS ester allows for labeling primary amines t-found in proteins, amine-modified oligonucleotides, and other molecules containing amines.
