Tetrazine-Acid
This product is a compact heterobifunctional reagent containing a tetrazine group and a terminal carboxylic acid. The tetrazine moiety supports ultrafast, copper-free inverse electron-demand Diels–Alder (IEDDA) ligation with strained alkenes such as TCO or BCN, while the carboxyl group couples readily with amines or activated esters. Its small, reactive design makes it especially useful for probe development, bioorthogonal chemistry, and controlled conjugation workflows.
