CBZ-AEP Usage And Synthesis

Description

3-[2-(Cbz-amino)ethoxy]propanoic acid is a PEG linker containing an carboxylic acid (CO2H) group and a benzyl (Cbz) protecting group. The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) forming a stable amide bond. The benzyl protecting group can be removed via hydrogenolysis to form a free amine.

Uses

Cbz-NH-PEG1-CH2CH2COOH is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
