Alkyne PEG Linker

Alkyne Linkers are a specialized subclass of bioorthogonal reagents containing terminal alkyne groups (-C≡CH) for copper-catalyzed or strain-promoted azide-alkyne cycloaddition. Representative structures like HC≡C-CH₂-PEGn-CH₂CH₂-COOH integrate polyethylene glycol spacers with carboxyl termini, enabling simultaneous bioconjugation and hydrophilic modulation for applications in biomolecular immobilization and nanomaterial functionalization.
