This chemical is primarily utilized in bioconjugation and protein modification applications. It serves as a crosslinking agent, enabling the attachment of biomolecules such as proteins, peptides, or antibodies to various surfaces or other molecules. The aminooxy group allows for efficient conjugation with carbonyl-containing compounds, while the pyrrole-2,5-dione moiety facilitates reactions with thiol groups. This dual functionality makes it valuable in creating stable, site-specific linkages in bioconjugation processes. It is often employed in the development of biosensors, drug delivery systems, and diagnostic assays, where precise and stable molecular interactions are critical. Additionally, it is used in research to study protein interactions and to immobilize biomolecules on solid supports for analytical purposes.
