Medchemexpress LLC Benzyl N-[2-[2-[2-(2-aminoethoxy)ethoxy]ethoxy]ethyl]carbamate | 863973-20-0 | MFCD28155474 | 95.0% | 326.39 g·mol⁻¹ | C16H26N2O5 | 100 MG
SDP

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.

Medchemexpress LLC Benzyl N-(2-{2-[2-(2-aminoethoxy)ethoxy]ethoxy}ethyl)carbamate | 863973-20-0 | MFCD28155474 | 99.0% | 326.39 g/mol | C16H26N2O5 | 500 MG
SDP

Benzyl N-(2-{2-[2-(2-aminoethoxy)ethoxy]ethoxy}ethyl)carbamate is a Cbz-protected PEG3 linker bearing a terminal primary amine. The hydrophilic PEG spacer improves aqueous solubility, while the Cbz protecting group enables controlled deprotection, making the reagent useful for installing amine-functional linkers in small-molecule conjugates, bioconjugation workflows, and PROTAC assemblies.

  • Cbz-protected terminal amine for orthogonal deprotection.
  • PEG3 spacer increases water solubility.
  • Primary amine handle for reliable conjugation chemistry.
  • Compatible with linker synthesis and bioconjugation workflows.
  • Available in laboratory-scale quantities for synthesis and screening.
