Mal-amido-PEG9-amine (TFA) is a PEG-based PROTAC linker that contains a maleimide moiety and a terminal amine present as the trifluoroacetic acid salt. It is designed as a hydrophilic spacer to connect ligands in bifunctional molecules and to enable selective thiol conjugation while providing an amine handle for further coupling reactions.
- Maleimide group enables selective thiol conjugation.
- Terminal amine (TFA salt) provides an amide-coupling handle.
- PEG9 spacer increases solubility and molecular flexibility.
- Suitable for assembly of bifunctional molecules such as PROTACs and bioconjugates.
- Available in small mg-scale quantities for research use.
