AZD-PEG13-PFP is a PEG linker containing one AZD group and one PFP ester group, which is an activated ester that reacts with a primary amine to form an amide bond. Science has found that PFP ester is more stable than other amine-reactive groups because it is less likely to undergo hydrolysis. Hydrophilic PEG spacers increase solubility in aqueous media.
