Boc-NH-PEG3 is a Boc-protected PEG3-based linker used for assembling PROTACs and other bioconjugates. It provides a Boc-protected terminal amine and a terminal hydroxyl, offering orthogonal functional handles for stepwise coupling. The short PEG3 spacer improves aqueous solubility and imparts flexible spacing between linked ligands.
- Boc-protected terminal amine enables selective deprotection and subsequent coupling.
- Terminal hydroxyl allows activation or conjugation chemistry.
- Short PEG3 spacer provides aqueous solubility and flexible linker geometry.
- High stated purity (98.0%) supports reproducible synthesis.
- Multiple pack sizes available for small-scale and preparative work.
