Used as a linker in bioconjugation, it facilitates the attachment of molecules like proteins, peptides, or antibodies to other entities such as drugs, dyes, or nanoparticles. The PEG chains enhance solubility and reduce immunogenicity, while the TFP ester group enables efficient and selective coupling to amine-containing molecules. This compound is particularly valuable in drug delivery systems, where it helps create targeted and stable conjugates for therapeutic applications. It is also employed in diagnostic imaging and research tools, enabling precise labeling and tracking of biomolecules.
