2-Amino-1,3-bis(t-butoxycarbonylethoxy)propane is a PEG linker containing an amino group with two t-butyl esters. The amino group is reactive with carboxylic acids, activated NHS esters. The t-butyl protected carboxyl groups can be deprotected under acidic conditions.

NH-bis(C1-PEG1-Boc) is an alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTACs[1].
