Cbz-NH-PEG4-C2-acid is a Cbz-protected PEG4 linker bearing a two-carbon carboxylic acid terminus and a benzyloxycarbonyl-protected amine. It functions as a flexible, hydrophilic spacer and synthetic building block for assembling proteolysis targeting chimeras (PROTACs) and other small-molecule bioconjugates, enabling orthogonal coupling strategies in multi-step syntheses.
- Cbz-protected amine for orthogonal coupling.
- Four-unit polyethylene glycol spacer for flexibility and solubility.
- Terminal two-carbon carboxylic acid for standard coupling chemistries.
- Suitable for PROTAC synthesis and small-molecule conjugation.
- Reported high purity to support reliable synthetic workflows.
