I. [Product Description]
SH-PEG-NBD (Thiol-Polyethylene Glycol-Nitrophenyloxadiazole) is a multifunctional organic intermediate with both efficient coupling ability and fluorescent labeling properties. Its core value lies in the excellent performance demonstrated in the surface engineering of biological materials and the construction of catalyst carriers through the directional modification of thiol groups and the steric hindrance effect of the PEG chain. At the same time, the nitrophenyloxadiazole group endows it with unique fluorescent response characteristics.
