Description

PEG8-Tos features a hydrophilic polyethylene glycol backbone paired with a tosylate leaving group, enabling efficient coupling in aqueous environments. This balance of solubility and reactivity supports streamlined synthesis in bioconjugation and polymer functionalization workflows.

Application

PEG8-Tos serves as a versatile, bench-stable linker for the synthesis of PEGylated small molecules and bioconjugates. Its tosylate group enables efficient nucleophilic substitution with amines, thiols, and alcohols under mild conditions, facilitating rapid conjugation workflows. The eight-ethylene glycol unit provides enhanced solubility and stability in aqueous environments, making it well-suited for applications in drug delivery and probe development.
