Mal-PEG3-NH2 TFA is a linear, heterobifunctional polyethylene glycol (PEG) crosslinker supplied as the trifluoroacetic acid (TFA) salt. It contains a maleimide at one end and a primary amine at the other, enabling thiol-to-amine conjugation and use as a non-cleavable linker in PROTAC and bioconjugation workflows. For research use only.

  • Provides maleimide and primary amine reactive groups for orthogonal conjugation.
  • PEG3 spacer improves aqueous solubility and reduces steric hindrance.
  • TFA salt form enhances stability and handling compared with the free base.
  • Non-cleavable linker suitable for stable conjugates and PROTAC constructs.
  • High purity (>99%) for consistent conjugation performance.
