NHS-PEG3-NHS, also known as Bis-PEG3-NHS ester, is a bifunctional PEG linker containing two NHS ester groups. The hydrophilic PEG spacer enhances the aqueous solubility of the compound, making it ideal for use in various bioconjugation applications. The NHS ester groups enable efficient and sequential conjugation with primary amines found in proteins, oligonucleotides, and other amine-containing molecules, forming stable amide bonds.

NHS-PEG3-NHS is a noncleavable 3-unit PEG linker used in antibody-drug conjugation (ADC).
