TCO-OH (axial)
TCO-OH (axial) is a high-purity strained cyclooctene derivative featuring an axial hydroxyl group specifically for versatile chemical modification. The trans-cyclooctene moiety specifically enables ultra-fast, catalyst-free inverse-electron-demand Diels–Alder (IEDDA) click reactions with tetrazines, ideal for bioorthogonal chemistry in living systems. The axial configuration offers distinct steric and reactivity properties that can especially enhance conjugation selectivity and kinetics.
