Dibenzocyclooctyne (ADIBO, DBCO) is one of the most reactive cycloalkynes for strain-promoted alkyne azide cycloaddition (SPAAC) — a copper-free click chemistry reaction.

DBCO reacts instantly with azides. The reaction rate is much higher than that of copper-catalyzed reaction, and reactions with many other cyclooctynes. Unlike some other cyclooctynes, DBCO does not react with tetrazines — this allows to carry out orthogonal conjugation of azides with DBCO, and trans-cyclooctenes with tetrazines.

This amine-reactive NHS ester provides easy attachment of the reactive moiety to almost any primary or secondary amine group, such as protein, peptide, or small molecule amine.
