Br-PEG6-C2-NHBoc（Cat No.:I044636）is a heterobifunctional polyethylene glycol (PEG) linker featuring a terminal bromo group and a Boc-protected amine, separated by a six-unit PEG chain and a two-carbon alkyl spacer. The bromo group allows nucleophilic substitution with thiols, amines, or other nucleophiles for covalent attachment, while the Boc-protected amine can be deprotected under acidic conditions to expose a primary amine for further functionalization. The PEG6 segment enhances hydrophilicity, flexibility, and biocompatibility. This reagent is widely used in bioconjugation, targeted drug delivery, and surface modification in biomedical and materials research.
