N-Boc-N-(DBCO-PEG4)-N-PEG4-t-butyl ester represents a branched PEG linker containing a DBCO moiety for click chemistry with azide-bearing entities, as well as t-butyl-protected carboxyl and Boc groups that can be deprotected under acidic conditions. Solubility in aqueous media is improved by the PEG chains. The branched structure permits conjugation to ADC payloads or other molecules of interest.
