I. [Product Description]
OPSS-PEG-Niacin is a multifunctional organic intermediate that enables efficient thiol coupling reactions through the o-pyridyl disulfide (OPSS) group. It is suitable for biomolecule modification and functional material synthesis. Its polyethylene glycol (PEG) segment imparts excellent water solubility and biocompatibility, and the niacin group can further expand targeted or functionalization applications. This compound is of great value in the fields of catalytic coupling reactions, nanocarrier construction, and surface modification.
