N-Me-N-bis-PEG4（Cat No.:I015887）is a bifunctional polyethylene glycol derivative consisting of a central N-methyl group substituted with two PEG₄ chains. The PEG arms impart excellent water solubility, flexibility, and biocompatibility, reducing nonspecific interactions and steric hindrance. With its neutral, hydrophilic structure, this reagent is particularly suited as a molecular spacer or building block in bioconjugation, materials science, and pharmaceutical research. It is often applied in nanoparticle engineering, hydrogel design, and drug delivery systems to enhance circulation, stability, and overall performance of biomolecular assemblies and functional materials.
