N-(t-butyl ester-PEG4)-N-bis(PEG4-Propargyl) is a trifunctional PEG linker that combines a t-butyl ester with two terminal alkynes. The alkynes can be applied in copper-click chemistry with azides to form stable triazole linkages with a target molecule, while the t-butyl ester can be deprotected and reacted with amines or alcohols to form amides or esters.
