DBCO Amine (CCT-A103)


DBCO Amine is a simple DBCO-containing building block used to derivatize carboxyl groups in the presence of activators (e.g. EDC, or DCC) or activated esters (e.g. NHS esters) with DBCO moiety through a stable amide bond.

DBCO reagents, also know as ADIBO or DIBAC are the most commonly used substrates for copper-free click reaction. DBCO compounds react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.
