I. [Product Description]
VA-PEG-Ornithine (CAS 70-26-8) is a high-purity organic intermediate prepared by precise coupling of valeric acid, polyethylene glycol (PEG), and ornithine. This compound combines the water-solubility advantage of the PEG segment and the active amino group property of ornithine. It can be used as a pharmaceutical intermediate for functional modification or as a carrier in catalytic systems to improve reaction efficiency.
