HO-PEG14-OH(CAT: R035733) is a linear polyethylene glycol (PEG) derivative with hydroxyl groups at both termini of a 14-unit PEG chain. This symmetrical, hydrophilic linker provides excellent aqueous solubility, flexibility, and low immunogenicity, making it ideal for chemical modification and bioconjugation. The terminal hydroxyls can be further functionalized into activated esters, amines, azides, or other reactive groups, enabling tailored applications. HO-PEG14-OH is widely used in drug delivery, PEGylation, surface coating, nanomaterials, and biomaterials research, where extended chain length and hydrophilicity are required. Its design ensures reduced steric hindrance and enhanced biocompatibility for use in advanced biomedical and material science applications.
