endo-BCN-PEG4-Tos is a heterobifunctional linker comprising a BCN moiety for copper-free click chemistry via strain-promoted azide–alkyne cycloaddition (SPAAC) and a tosylate group for further functionalization. The hydrophilic PEG3 chain enhances solubility, reduces steric hindrance, and minimizes aggregation.
