Boc-NH-PEG4 (PROTAC Linker 12) is a Boc-protected PEG4 linker with a tert-butoxycarbonyl-protected amine and a terminal hydroxyl. It provides a short, hydrophilic PEG spacer commonly used to connect ligands in PROTACs and other bifunctional molecules, improving solubility and enabling modular conjugation chemistry.
- Boc-protected amine enables selective deprotection and downstream coupling.
- Terminal hydroxyl allows diverse functionalization and linker attachment.
- PEG4 spacer increases aqueous solubility and flexibility in conjugates.
- High reported purity supports reproducible synthesis and analysis.
- Suitable for synthesizing PROTACs and bifunctional degraders.
