This compound is widely used in bioconjugation and click chemistry applications due to its DBCO (dibenzocyclooctyne) group, which reacts efficiently with azides without the need for a catalyst. Its PEG3 spacer enhances solubility and flexibility, making it suitable for modifying biomolecules like proteins, peptides, and antibodies. It is particularly valuable in drug delivery systems, where it facilitates the targeted attachment of therapeutic agents. Additionally, it is employed in the development of diagnostic probes and imaging agents, enabling precise labeling and detection in biological studies. Its amine group allows further functionalization, expanding its utility in creating complex molecular architectures for research and therapeutic purposes.
