Methyltetrazine is typically used in the inverse electron demand Diels Alder (iEDDA) reaction, a reaction where tetrazine compounds react with strained dienophiles, such as trans cyclooctene (TCO) or norbornene derivatives. It is widely used for bioconjugation, fluorescent labeling, and live cell imaging due to its high reactivity,
