NH-bis(PEG2-OH) is widely used in the field of bioconjugation and drug delivery due to its water-soluble and biocompatible properties. It serves as a linker molecule in the development of antibody-drug conjugates (ADCs), enabling the attachment of therapeutic agents to antibodies for targeted cancer treatments. The compound is also utilized in the modification of peptides and proteins to enhance their stability and solubility in aqueous environments. Additionally, it plays a role in the synthesis of hydrogels and biomaterials, where its PEG (polyethylene glycol) segments contribute to improved biocompatibility and reduced immunogenicity. In nanotechnology, NH-bis(PEG2-OH) is employed to functionalize nanoparticles, ensuring better dispersion and targeted delivery in biomedical applications. Its ability to form stable bonds with various biomolecules makes it a valuable tool in pharmaceutical research and development.
