2-((Azido-PEG12-carbamoyl)methoxy)acetic acid is a PEG linker featuring an azide group and a terminal carboxylic acid. The azide reacts with alkyne, BCN, or DBCO via Click Chemistry, while the carboxylic acid forms stable amide bonds with primary amines in the presence of activators like EDC or HATU. Its hydrophilic PEG spacer enhances aqueous solubility.
