NH-Bis-m-PEG4
NH-Bis-m-PEG4 is a high-purity bifunctional PEG linker with two methoxy-terminated PEG4 chains connected to a central amine. The PEG4 arms enhance solubility and flexibility, while the central amine enables efficient conjugation to electrophiles. This structure is especially ideal for improving hydrophilicity and reducing aggregation in bioconjugation and material science applications.
