m-PEG6-Tos(CAT: I017017) is a monofunctional polyethylene glycol (PEG) derivative featuring a tosyl (tosylate) leaving group at one terminus of a six-unit PEG chain. The tosyl group serves as an excellent electrophile for nucleophilic substitution, enabling efficient modification with amines, thiols, alkoxides, and other nucleophiles. The PEG6 spacer provides enhanced solubility, hydrophilicity, and flexibility, reducing steric hindrance in conjugation reactions. m-PEG6-Tos is widely used in bioconjugation, polymer chemistry, surface functionalization, and materials science, where precise PEGylation and linker chemistry are required. Its design makes it a versatile building block for constructing stable, hydrophilic, and functionalized biomolecules or materials.
