N-(Hydroxy-PEG3)-N-bis(PEG4-t-butyl ester) is a branched PEG analogue with a terminal hydroxy group and two t-butyl esters. The hydroxy group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl groups can be deprotected under mild acidic conditions.
