m-PEG2-O-Ph-NH2（Cat No.:I044721）is a functionalized compound combining a short polyethylene glycol (PEG2) chain with a phenyl ring and a terminal amine group. The PEG2 spacer enhances water solubility, flexibility, and biocompatibility, reducing steric hindrance and nonspecific binding in biological systems. The phenyl ring provides structural rigidity, while the para-positioned amine group enables further conjugation through amide bond formation or other coupling chemistries. This molecule is valuable in drug delivery, bioconjugation, and material surface modification, supporting the creation of targeted, hydrophilic constructs in biomedical and chemical research applications.
