Amino-PEG2-acid (NH2-PEG2-COOH), a PEG reagent, features an amino group and terminal carboxylic acid, enhancing solubility and reactivity in aqueous environments. Its amino group reacts with various functional groups, while the terminal carboxylic acid forms stable amide bonds with primary amines using activators like EDC or HATU. Amino-PEG2-acid serves as a cleavable 3-unit PEG ADC linker for antibody-drug conjugate (ADC) synthesis and functions as a PEG-based PROTAC linker for PROTAC synthesis.
