HO-PEG17-OH(CAT: I016350) is a linear, bifunctional polyethylene glycol (PEG) derivative with hydroxyl groups at both termini of a 17-unit PEG chain. The terminal hydroxyls serve as versatile reactive handles that can be further functionalized into esters, ethers, carbamates, or other derivatives. The PEG17 backbone provides excellent hydrophilicity, flexibility, and water solubility, making it an ideal spacer or scaffold for chemical modifications. Its long PEG chain reduces steric hindrance, minimizes non-specific interactions, and enhances biocompatibility. HO-PEG17-OH is widely used in polymer chemistry, surface engineering, biomaterials development, and drug delivery systems where extended, modifiable PEG spacers are required.
