Description

Tos-PEG2-NH-Boc features a bis(tert-butoxycarbonyl)amino terminus linked via a short PEG spacer to a tosyl group, enabling dual protection for amine functionalities. This bifunctional reagent integrates seamlessly into peptide synthesis workflows, offering orthogonal handling and controlled deprotection under mild conditions.

Application

Tos-PEG2-NH-Boc serves as a versatile bifunctional building block for peptide and oligonucleotide conjugation, combining a tosyl (Tos) leaving group with a PEG2 spacer and a Boc-protected amine. The Tos group enables efficient nucleophilic substitution with amines or thiols, while the PEG2 spacer enhances solubility and reduces aggregation. The Boc-protected amine offers orthogonal handling in multi-step syntheses, facilitating selective deprotection and coupling under standard conditions. This reagent supports reliable functionalization in solid-phase and solution-phase workflows.
