Azide PEG Linker

Azide Linkers are a specialized subclass of click chemistry reagents featuring terminal azide groups (-N₃) that enable efficient cycloaddition reactions with alkynes. Typical structures like N₃-PEGn-OH incorporate polyethylene glycol spacers to enhance solubility and biocompatibility, making them particularly valuable for bioconjugation, surface modification, and pharmaceutical labeling applications.
