Used in bioorthogonal chemistry for selective labeling of biomolecules due to its fast inverse electron-demand Diels-Alder reaction with strained alkenes and alkynes. Enables live-cell imaging, protein tagging, and targeted delivery in biological systems without interfering with native biochemical processes. Also applied in materials science for constructing functional surfaces and responsive polymers through click chemistry. Its fluorinated structure enhances stability and modulates electronic properties, making it suitable for developing sensors and optoelectronic materials.
