I. [Product Description]
Bis-PEG2-NHS (CAS: 1008402-79-6) is a highly efficient bis-amino-dimeric polyethylene glycol-succinimidyl ester cross-linking agent. It can be used as an organic intermediate or a pharmaceutical intermediate, and is widely applied in bioconjugation reactions and the synthesis of polymer materials. The PEG segments in its structure significantly enhance water solubility and biocompatibility, and the NHS active groups ensure efficient coupling with amino groups. It is a key catalyst or linker in fields such as protein modification and the construction of nanocarriers.
