Hydroxy-PEG12-Boc(CAT: I016926) is a monofunctional polyethylene glycol (PEG) derivative designed for advanced bioconjugation and chemical synthesis. It features a terminal hydroxyl group for further derivatization and a Boc-protected amine at the opposite end, enabling controlled deprotection and subsequent coupling reactions. The PEG12 spacer provides excellent aqueous solubility, enhanced flexibility, and reduced steric hindrance, making it suitable for conjugating biomolecules, drugs, or surface ligands. Hydroxy-PEG12-Boc is widely applied in drug delivery, PEGylation, surface modification, and materials research, offering reliable performance in applications that require hydrophilicity, stability, and extended linker length for optimal molecular interactions.
