m-PEG4-t-butyl ester Chemical Properties, Uses, Production

Description

m-PEG4-t-butyl ester is a PEG linker containing a t-butyl ester. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media.

Uses

m-PEG4-Boc is a cleavable 4 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. m-PEG4-Boc is also a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[2].

IC 50

PEGs; Cleavable Linker
