NHS-PEG5-NHS (CAS: 756526-03-1) is a PEG-based linker featuring two NHS ester groups. The PEG spacer enhances the compound's solubility in aqueous environments. The NHS ester groups are highly reactive with primary amines (-NH2), making this linker ideal for labeling proteins, amine-modified oligonucleotides, and other amine-containing molecules. This functionality facilitates efficient bioconjugation and is widely used in biochemical research and molecular biology applications.
