3-(Azido-PEG5-amino)propanol is a PEG linker containing an azide moiety and a terminal hydroxyl group. The azide is commonly used in click chemistry withwith alkynes, DBCO and BCN to form triazole linkages. The hydroxyl group can be derivatized to other reactive functional groups. The seconary amine group can be utilized to conjugate with a third molecule of interest, such as target specific probes and flurorescent dye probes. The hydrophilic PEG spacer can increase the water solubility of compounds in aqueous media.
