I. [Product Description]
NHS-PEG-TK-COOH is a multifunctional organic intermediate that integrates the efficient coupling ability of N-hydroxysuccinimide ester (NHS), the excellent water solubility and steric hindrance effect of polyethylene glycol (PEG), and the pH-responsive properties of ketal thiol (TK). This compound can be used as a pharmaceutical intermediate or a catalyst carrier for bioconjugation reactions, suitable for the precise construction of complex molecular structures and the development of controlled release systems.
