Application

DBCO Acid is a bifunctional building block comprising of an acid terminus useful for reaction with amine containing linkers in presence of activators such as EDC or HATU and a dibenzocyclooctyne (DBCO) terminus useful for copper-free click chemistry.

Features and Benefits

DBCO compounds react with azides without need of Cu(I) catalyst due to the strained nature of alkyne resulting in formation of fast and stable triazole linkage.

Chemical reactions that enable selective biomolecule labeling in living organisms offer a means to probe biological processes in vivo. Very few reactions possess the requisite bioorthogonality, and, among these, only the Staudinger ligation between azides and triarylphosphines has been employed
