Azido-PEG3-acid is a non cleavable 3-unit PEG ADC connector used to synthesize antibody drug conjugates; Crosslinking agent containing azide (N3) and carboxylic acid (CO2H). The terminal carboxylic acid reacts with the primary amine group in the presence of an activator (EDC or HATU) to form a stable amide bond. The hydrophilic PEG spacing increases the solubility in the medium.
