I. [Product Description]
OPSS-PEG-Rhodamine B (o-Pyridyl Disulfide/Thiopyridine) is a multifunctional organic intermediate with both high catalytic activity and precise molecular coupling ability. It is widely used in the fields of bioconjugation reactions and polymer material synthesis. The adjustability of the PEG chain in its structure and the active sites of o-pyridyl disulfide/thiopyridine make it a key component in the development of pharmaceutical intermediates and the preparation of functional materials.
