I. [Product Description]
NHS-PEG-CH₂CH₂COOtBu is a multifunctional organic intermediate that combines the high reactivity of N-hydroxysuccinimide ester (NHS) with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). This compound can serve as an efficient coupling or modifying agent, and is widely used in the cross-linking of biological macromolecules, the synthesis of functionalized materials, and the construction of catalyst carriers. It is a key reagent in the development of pharmaceutical intermediates.
