I. [Product Description]
NHS-PEG-TK-SHN-N-hydroxysuccinimide ester-polyethylene glycol-ketal thiol-mercapto is a multifunctional organic intermediate with both high catalytic activity and precise molecular coupling ability. Its core value lies in the controllable cleavage characteristics of the ketal thiol (TK) group and the high reactivity of the NHS ester. It is suitable for constructing dynamic responsive bio-coupling systems and is a key component in the development of pharmaceutical intermediates and the synthesis of polymer materials.
