Amine-PEG8-Amido-tri-(carboxyethoxymethyl)-methane, HCl salt is a tetrafunctional PEG linker including three terminal caboxyl groups, which can react with primary amine groups in the presence of activators such as HATU, and terminal amine for coupling with an NHS ester to form an amide bond. The PEG8 linker improves the hydrophilicity of the compound.
