m-PEG2-amine is a high-purity, monofunctional PEG linker featuring a short PEG2 spacer and a reactive primary amine group. The PEG spacer specifically enhances solubility and flexibility, while the amine enables efficient coupling to electrophiles such as activated esters, making it ideal for bioconjugation, PEGylation, and surface functionalization applications where minimal spacer length is preferred.
