Tos-PEG6-OH(Cat No.:I016020)is a heterobifunctional polyethylene glycol derivative featuring a tosyl (Tos) leaving group at one end and a hydroxyl group at the other, connected by a six-unit PEG chain. The tosyl group serves as a highly reactive handle for nucleophilic substitution, enabling efficient introduction of diverse functional groups. The hydroxyl terminus offers additional opportunities for chemical modification or coupling. The PEG6 spacer enhances solubility, flexibility, and biocompatibility while reducing steric hindrance. Widely applied in bioconjugation, peptide synthesis, and materials science, this reagent supports multifunctional biomolecule and linker design.
