Description General description 4-(1,2,4,5-Tetrazin-3-yl)phenyl)methanamine is a 1,2,4,5-tetrazine derivative capable of undergoing [4+2] Diels-Alder cycloaddition reactions with strained alkenes, which makes it highly useful in bioorthogonal labeling and cell detection applications. Application Amine functionalized tetrazine for inverse electron demand Diels-Alder cycloaddition reactions. The tetrazine will react with strained alkenes such as transcyclooctene, norbornene and cyclopropene to yield a stable covalent linkage. Tetrazines have proven useful in bioorthogonal reactions for many biological imaging and bioconjugation applications. Packaging 10, 25 mg in clear glass bottle
