N-Boc-N-bis(PEG8-acid) is a bifunctional PEG linker with two carboxylic acids and an N-Boc protected secondary amine. The carboxylic acids are most frequently used to couple with alcohols and amines while the Boc-amine can be deprotected in acid and applied as a nucleophile to form a trifunctional molecule.
