N-(DBCO)-N-bis(PEG4-Amine) is a trifunctional reagent with two primary amines and a DBCO moiety annealed to a central tertiary amine. The DBCO is a strained cyclooctyne, perfect for labeling azide residues on a target molecule using click chemistry, while the primary amines can be used for reactions with carboxylic acids, aldehydes, or ketones.
