Tos-PEG2-Boc features a protected amine group flanked by two ethylene glycol units, offering enhanced solubility in polar solvents. The tosyl (Tos) moiety provides stability and facilitates selective deprotection under mild conditions. This bifunctional linker enables efficient conjugation workflows in peptide synthesis and bioconjugation applications.
Tos-PEG2-Boc serves as a versatile bifunctional building block for peptide and oligomer synthesis, combining the stability of a tert-butoxycarbonyl (Boc) protecting group with a tosyl (Tos) leaving group on a short PEG2 spacer. It enables efficient coupling reactions, facilitates purification via ion-exchange chromatography, and supports orthogonal deprotection strategies in complex molecule assembly.
