N-(Hydroxy-PEG3)-N-bis(PEG4-t-butyl ester) Chemical Properties, Uses, Production

Description

N-(Hydroxy-PEG3)-N-bis(PEG4-t-butyl ester) is a branched PEG linker 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.

Uses

N-(Hydroxy-PEG3)-N-bis(PEG4-Boc) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

IC 50

PEGs; Alkyl/ether
