Gly-PEG3-endo-BCN TFA salt is a BCN PEG linker that contains a Boc-protected glycine moiety. While the BCN group readily undergoes click chemistry with azide-bearing biomolecules, the protected glycine amine can be easily deprotected under mild acidic conditions to form free amine. The versatile amine group can undergo conjugation with a variety of carbonyl-, acid and activated esters.
