Benzyl-PEG1-Tos serves as a reactive linker for conjugation workflows, featuring a tosylate group that facilitates efficient coupling with nucleophiles. The benzyl-protected PEG1 spacer provides enhanced solubility and stability under standard conditions, enabling straightforward integration into peptide or small-molecule synthesis.
Benzyl-PEG1-Tos serves as a versatile bifunctional building block for peptide and small-molecule conjugation. The benzyl group provides a stable, orthogonal handle for selective deprotection, while the PEG1 spacer offers enhanced solubility and reduced aggregation. The tosyl (Tos) group functions as a reliable leaving group in nucleophilic substitution reactions, enabling efficient coupling under mild conditions. This compound facilitates site-specific modifications in synthetic chemistry workflows with excellent bench stability and straightforward purification.
