DBCO-PEG4-NH2 (CAS NO.: 1255942-08-5) is a monodispersed PEG chain terminated with a DBCO (dibenzocyclooctyne) functional group at one end and an amino group (NH2) at the other end. The DBCO group facilitates selective and rapid click chemistry reactions with azide-functionalized molecules via strain-promoted azide-alkyne cycloaddition (SPAAC), allowing for site-specific labeling, immobilization, or conjugation. The amino group provides an additional reactive site for conjugation with carboxyl, aldehyde, or other activated functional groups, enabling further customization of biomolecules.
