This chemical is widely used in bioconjugation and click chemistry applications. It serves as a linker molecule, enabling the attachment of biomolecules such as peptides, proteins, or antibodies to other functional groups or surfaces. The DBCO (dibenzocyclooctyne) group allows for strain-promoted azide-alkyne cycloaddition (SPAAC), a type of click reaction that is highly efficient and does not require a catalyst. The PEG4 spacer provides flexibility and solubility, enhancing the stability and functionality of the conjugated molecules. The NH-Boc (amine-protected with tert-butyloxycarbonyl) group allows for further chemical modifications after deprotection, making it versatile for multi-step synthesis. It is particularly valuable in drug delivery systems, diagnostic probes, and the development of bioconjugated materials for research and therapeutic purposes.
