PEG4 diazide is a hydrophilic linker with two azide groups. Both can be modified by click chemistry, either by a copper catalyzed reaction with terminal alkynes, or by a copper-free reaction with cycloalkynes. Azides can also participate in the Staudinger ligation reaction.

This diazide is useful for the synthesis of dimeric molecules by click chemistry.
