I. [Product Description]
Br-PEG-Biotin (Bromide-Polyethylene Glycol-Biotin) is a bifunctional organic intermediate that combines the high reaction activity of bromide with the high specific binding ability of biotin. As a pharmaceutical intermediate and bioconjugation catalyst, its PEG chain can significantly improve water solubility and molecular compatibility, and it is widely used in the fields of biomolecular labeling and nanomaterial functionalization.
