I. [Product Description]
Bis-NH2-C1-PEG Biotin-Polyethylene Glycol-NHS Ester (CAS 34246-51-9) is a multifunctional organic intermediate. Through the bifunctional reaction sites of amino group (NH2) and NHS ester group, it enables efficient coupling and modification of biomolecules. Its core value lies in its excellent biocompatibility and adjustable PEG chain length. It can serve as a key catalyst or linker for the surface functionalization of biomaterials and the preparation of nano drug carriers, and is suitable for the directional construction of complex systems.
