DBCO-PEG6-amine (CAS No.: 2353409-98-8) is a functional molecule containing a dibenzocyclooctyne (DBCO) group and a hexaethylene glycol (PEG6) segment, with an amino group (-NH₂) at the terminal end. Its molecular formula is C₃₃H₄₅N₃O₈, molecular weight 611.73, purity ≥95%, and it appears as a white to pale yellow solid at room temperature. The production process involves chemically synthesizing the DBCO group and PEG6 segment into a covalent bond, followed by introducing an amino group to enhance reactivity. This molecule, leveraging the copper-free click reaction capability of the DBCO group, can efficiently couple with azide groups. Additionally, the amino group supports reactions with carboxyl groups, activated esters, and other groups. It is widely applied in the synthesis of PROTAC molecules, construction of drug delivery systems, and development of biosensors.
