Iodo-PEG7-alcohol（Cat No.:I045197）is a polyethylene glycol (PEG) derivative containing seven ethylene glycol units, terminated with an iodine atom on one end and a hydroxyl group on the other. The PEG7 spacer imparts hydrophilicity, flexibility, and enhanced solubility, while the iodine atom enables efficient alkylation or substitution reactions for covalent attachment to various biomolecules or surfaces. The terminal hydroxyl group allows further functionalization for conjugation or polymer modification. Iodo-PEG7-alcohol is widely used in bioconjugation, drug delivery, and material science to improve pharmacokinetics, reduce immunogenicity, and optimize spatial orientation in chemical and biomedical applications.
