Methyltetrazine-NHS ester

Methyltetrazine-NHS Ester is a heterobifunctional reagent combining a methyltetrazine group for bioorthogonal cycloaddition with an NHS ester for efficient amine coupling. Methyltetrazine-NHS Ester enables rapid, catalyst-free conjugation to strained alkenes/alkynes while facilitating stable amide bond formation with primary amines. Methyltetrazine-NHS Ester is widely used in live-cell imaging, pretargeted strategies, and biomolecule functionalization where fast kinetics are critical.
