NH-bis(C1-PEG1-Boc)（Cat No.:I016072）is a compact bifunctional linker featuring a central amine core connected to two short C1-PEG1 arms, each terminating in a Boc-protected amine. The Boc groups serve as removable protecting functionalities, which can be cleaved under mild acidic conditions to yield reactive primary amines for further conjugation with carboxylic acids, activated esters, or isocyanates. The short C1-PEG1 spacers provide limited but effective hydrophilicity, while minimizing steric hindrance and maintaining reactivity. This reagent is valuable for controlled multivalent coupling in drug conjugates, polymer modification, and chemical biology applications.
