A new class of bioorthogonal reagents, 1,2,4-triazines, is described. These scaffolds are Stable in biological media and capable of robust reactivity with trans-cyclooctene (TCO). The enhanced stability of the triazine scaffold enabled its direct use in recombinant protein production. The triazine-TCO reaction can also be used in tandem with other bioorthogonal cycloaddition reactions. These features fill current voids in the bioorthogonal toolkit.
