NH-bis(PEG3-Boc)（Cat No.:I014521）is a bifunctional PEG-based reagent featuring a central amine core linked to two PEG3 arms, each capped with a Boc-protected amine group. The Boc functionalities serve as removable protecting groups, cleavable under mild acidic conditions to yield reactive primary amines for further derivatization with carboxylic acids, activated esters, or isocyanates. The PEG3 spacers enhance solubility, flexibility, and reduce steric hindrance, ensuring efficient coupling in diverse chemical environments. This reagent is widely applied in bioconjugation, polymer modification, drug development, and advanced chemical biology requiring orthogonal multivalent amine handles.
