Amine-PEG8-Picolyl azide, HCl salt constitutes a bifunctional PEG linker with the picoyl azide moiety increasing the efficiency and speed of the CuAAC reaction for improved biocompatible labeling, and the amine moiety to react with carboxylic acids in the presence of activators like HATU. Hydrophilicity is improved via the PEG linker. Reagent grade, for research use only.
