Description

General description

Dibenzocyclooctyne-amine (DBCO-NH2), is a heterobifunctional linker containing a DBCO moiety commonly used for the site-specific functionalization of nanobodies, enabling the addition of reactive DBCO groups for subsequent click chemistry reactions.

Application

Dibenzocyclooctyne-amine can be used as a :

• Linker to link azide-containing functional groups. It facilitates the formation of linkages through Strain-promoted azide-alkyne cycloaddition reactions (SPAAC)
• Reagent in the synthesis of N-heterocyclic carbene metal thiolates. It functionalizes the metal complexes and increases their reactivity in the strain-promoted alkyne–azide cycloaddition (SPAAC) reactions
• Amine functionalized cyclooctyne derivative. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions. This dibenzocyclooctyne will react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.
