S-acetyl-PEG4-amine (TFA) is a PEG-based PROTAC linker used in the chemical synthesis of proteolysis-targeting chimeras (PROTACs). PROTACs are heterobifunctional molecules that recruit an E3 ubiquitin ligase to a target protein, promoting ubiquitination and proteasomal degradation of the target.

  • Provides a short PEG4 spacer to control linker length and flexibility.
  • Contains a terminal amine (supplied as the TFA salt) for amide coupling and other conjugation chemistries.
  • Features an S-acetyl protecting group to allow selective deprotection strategies.
  • Available in small-quantity packages suitable for synthesis optimization and screening.
