I. [Product Description]
VS-PEG-NTA (Vinyl Sulfone-Polyethylene Glycol-Nitrilotriacetic Acid) is a multifunctional organic intermediate that combines biocompatible modification and metal chelation properties. Its vinyl sulfone group enables efficient coupling reactions, the PEG chain enhances water solubility and stability, and the NTA group is dedicated to the specific binding of transition metal ions. It is widely used in the fields of bioconjugation, catalyst support construction, and pharmaceutical intermediate synthesis.
