N-Mal-N-bis(PEG2-NH-Boc)

N-Mal-N-bis(PEG2-NH-Boc) is a branched maleimide reagent with a terminal maleimide group and two terminal Boc protected amino groups. Maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule . Boc can be deprotected under acidic conditions.

N-Mal-N-bis(PEG2-NH-Boc) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
