Boc-NH-PEG2-NH-Boc(CAT: I016595) is a symmetric, bifunctional polyethylene glycol (PEG) derivative featuring two tert-butoxycarbonyl (Boc)-protected amine groups linked by a short PEG2 spacer. The Boc groups provide temporary protection, enabling selective deprotection and controlled functionalization, while the PEG2 chain enhances solubility, flexibility, and reduces steric hindrance. This reagent is widely used as a versatile building block in peptide synthesis, linker design, and bioconjugation strategies. Its defined length makes it ideal for introducing short, hydrophilic spacers between functional moieties. Boc-NH-PEG2-NH-Boc supports applications in synthesis chemistry, drug delivery research, and biomedical material engineering where precise PEGylation is required.
