CbzNH-PEG3-CH2CH2NH2 is a Cbz-protected PEG3 amine linker (benzyl N-[2-[2-[2-(2-aminoethoxy)ethoxy]ethoxy]ethyl]carbamate) used as a hydrophilic spacer in bioconjugation. It provides a terminal primary amine for conjugation while the carbobenzyloxy (Cbz) group protects the opposing amine during multistep synthesis. Common applications include linker design for PROTACs, peptide and small-molecule conjugation, and other bioconjugation workflows.

  • Provides a hydrophilic PEG3 spacer to improve aqueous solubility.
  • Contains a terminal primary amine for standard coupling reactions.
  • Includes a Cbz protecting group for orthogonal amine protection.
  • Available in research-scale quantities suitable for synthesis and screening.
  • Typically supplied with high reported purity; consult the batch COA for exact value.
