Tos-PEG3-NH-Boc features a triethylene glycol spacer flanked by a tosyl-activated amine and a Boc-protected nitrogen, enabling sequential conjugation in peptide and biomolecule synthesis. This bifunctional linker combines solubility, stability, and orthogonal reactivity for efficient coupling workflows.
Tos-PEG3-NH-Boc serves as a versatile bifunctional building block for peptide and oligonucleotide conjugation, combining a tosyl (Tos) leaving group with a PEG3 spacer and a Boc-protected amine. The Tos group enables efficient nucleophilic substitution under mild conditions, while the PEG3 chain enhances solubility and reduces aggregation. The Boc-protected amine allows for selective deprotection and further functionalization, facilitating modular synthesis of bioconjugates and drug delivery systems.
