Boc-NH-PEG15-NH2（Cat No.:I016073）is a heterobifunctional PEG linker featuring a Boc-protected amine on one terminus and a free primary amine on the other, connected by a PEG15 chain. The Boc group provides temporary protection, removable under mild acidic conditions to reveal a second reactive amine. The free amine readily couples with carboxylic acids, activated esters, or isocyanates to form stable linkages. The long PEG15 spacer enhances hydrophilicity, increases molecular flexibility, and minimizes steric hindrance. This reagent is ideal for bioconjugation, drug delivery, polymer modification, and advanced biomaterials engineering.
