m-PEG2-O-Ph-3-NH2（Cat No.:I044720）is a multifunctional compound featuring a methoxy-terminated PEG2 (diethylene glycol) chain linked to a phenyl ring with an amine substituent at the meta (3) position. The PEG2 segment imparts hydrophilicity and flexibility, enhancing solubility and reducing nonspecific interactions. The methoxy end blocks further PEG extension, while the aromatic amine offers a reactive site for conjugation with electrophiles such as activated esters or isocyanates. This structure is useful in biomedical research, drug delivery, and materials science for functionalizing surfaces, labeling biomolecules, and constructing targeted, hydrophilic conjugates with controlled spatial arrangement.
