This compound is widely utilized in bioconjugation and chemical biology due to its unique structure. It serves as a linker for attaching biomolecules, such as proteins or peptides, to other functional groups or surfaces. The aminooxy group enables selective conjugation with carbonyl-containing molecules, while the PEG (polyethylene glycol) chains enhance solubility and reduce immunogenicity. The propargyl groups allow for click chemistry reactions, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating efficient and specific binding. This makes it valuable in drug delivery systems, diagnostic assays, and the development of targeted therapeutics. Its modular design also supports the creation of complex biomolecular architectures for research and industrial applications.
