N-(Boc-PEG3)-N-bis(PEG2-alcohol)(CAT: I016557) is a multifunctional polyethylene glycol derivative featuring a Boc-protected amine and two terminal hydroxyl groups. The PEG3 and PEG2 spacers enhance water solubility, flexibility, and reduce steric hindrance, making the molecule well-suited for versatile bioconjugation strategies. The Boc group provides a protected amine that can be selectively deprotected for controlled coupling, while the hydroxyl functionalities serve as handles for further derivatization or activation. This reagent is particularly valuable for constructing branched linkers, developing multifunctional probes, and enabling orthogonal conjugation in chemical biology, drug delivery, and biomaterial engineering applications.
