Used as a specialty crosslinking agent in advanced polymer synthesis, particularly in the development of functionalized hydrogels and bioconjugates. Its strained bicyclic alkyne structure enables efficient click chemistry reactions, making it valuable in bioorthogonal labeling applications for pharmaceutical research and diagnostic probes. Commonly employed in controlled drug delivery systems due to its ability to form stable, reversible bonds under physiological conditions. Also utilized in surface modification of biomaterials to enhance biocompatibility and enable site-specific immobilization of peptides or proteins.
