N-(Amino-PEG3)-N-bis(PEG3-t-butyl ester) is a 3-arm PEG linker consisting of an amino group with two t-butyl esters. The amino (NH2) groups is reactive with activated NHS esters or carboxylic acid. The t-butyl protected carboxyl group can be deprotected under acidic conditions.

N-(Amino-PEG3)-N-bis(PEG3-Boc) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
