I. [Product Description]
Tosylate-PEG-NTA is a multifunctional organic intermediate. It enables efficient coupling reactions through the tosylate group, and the NTA group provides excellent metal ion chelating ability. The adjustable length of its PEG chain makes it of great value in the fields of bioconjugation, catalytic system construction, and material surface modification. It is suitable for the synthesis of pharmaceutical intermediates and the development of catalyst carriers.
