Azido-PEG7-azido CAS:225523-86-4 is a long-chain, monodisperse PEG linker with a hydrophilic linker with two azide groups. Both can be modified by click chemistry, either by copper-catalyzed reactions with terminal alkynes, or by copper-free reactions with cycloalkynes. Azides can also participate in the Staudinger ligation reaction.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
