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. The PEG (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, making it ideal for linking biomolecules such as proteins, peptides, or antibodies. It is particularly useful in drug delivery systems, where it facilitates the targeted attachment of therapeutic agents to specific cells or tissues. Additionally, it is employed in the development of biosensors, diagnostic tools, and imaging probes, enabling precise labeling and detection of biological molecules. Its amine group allows for further functionalization, expanding its utility in various research and industrial applications.
