Boc-C1-PEG3-C4-OH(CAT: I017546) is a polyethylene glycol (PEG)-based linker containing a Boc-protected amino group, a triethylene glycol (PEG3) spacer, and a butyl hydroxyl terminus. The Boc (tert-butoxycarbonyl) group offers controlled amine protection for stepwise synthesis, while the PEG segment enhances hydrophilicity, solubility, and flexibility. The hydroxyl end allows further chemical modification or conjugation, making it a versatile intermediate. This bifunctional reagent is widely employed in peptide synthesis, drug delivery, bioconjugation, and material chemistry, where precise spacing and water solubility are crucial. Boc-C1-PEG3-C4-OH is a valuable building block for linker design and biomedical research applications.
