What is DBCO-Acid?

Description

DBCO-Acid is a non-activated building block and adds minimal spacer to modified molecules. In the presence of activators such as EDC or HATU, this reagent can be used to derivatize amine-containing molecules through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions.

The Uses of DBCO-Acid

DBCO-Acid is a reactant in the synthesis of high-generation polyester dendrimers. Also used in the preparation of modular, plasmin sensitive, clickable poly(ethylene glycol)-heparin-laminin microsphere systems for creating growth factor gradients in peripheral nerve regeneration.

General Description

Acid functionalized cyclooctyne derivative. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne click chemistry reactions. This azadibenzocyclooctyne will react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.
