Hydroxy-PEG4-CH2-Boc features a hydroxyl-terminated PEG4 spacer linked to a Boc-protected amine via a methylene bridge. This bifunctional intermediate enables controlled conjugation and protection in peptide synthesis and bioconjugation workflows. The hydrophilic PEG chain enhances solubility, while the stable Boc group allows for selective deprotection under mild acidic conditions.
Hydroxy-PEG4-CH2-Boc serves as a versatile, bench-stable building block for the synthesis of PEGylated compounds and bioconjugates. The hydroxyl group enables straightforward derivatization, while the Boc-protected amine offers orthogonal functionality for selective coupling. Its PEG4 spacer provides enhanced solubility and reduced aggregation, facilitating purification and downstream applications in medicinal chemistry and polymer science.
