Tetrazine-PEG4-amine is a heterobifunctional linker with a tetrazine for inverse electron demand Diels-Alder reactions and an amine end. It reacts with strained alkenes, producing a stable dihydropyridazine linkage. Boasting rapid kinetics and selectivity, it allows conjugation in complex aqueous environments. Its bioorthogonal nature ensures selectivity and biocompatibility in functionalized biological systems, even living organisms. Key applications include fluorescent imaging, drug delivery, and various imaging and therapy techniques.
